This listener correctly removes itself when the abort fires, but it was never removed when rendering **completed normally** (via `onAllReady`) or **failed fatally** (via `onFatalError` / `onShellError`).\n\nThis caused a memory leak: as long as the `AbortSignal` was alive, it held a reference to the listener closure, which in turn held a reference to the entire Fizz `request` object (which holds the entire server render state).\n\n**Fix:** Introduce a `cleanupSignalListener` callback scoped to each render function. The callback is assigned to call `signal.removeEventListener` after the listener is registered, and is invoked from all terminal states:\n- `onAllReady` — rendering completed successfully\n- `onFatalError` — fatal render error (also covers `onShellError` which triggers `onFatalError`)\n- `onShellError` — shell render failed (defensive, since `onFatalError` is also called)\n\n**Files affected:**\n- `ReactDOMFizzServerBrowser.js` (`renderToReadableStream`, `resume`)\n- `ReactDOMFizzServerEdge.js` (`renderToReadableStream`, `resume`)\n- `ReactDOMFizzServerBun.js` (`renderToReadableStream`)\n- `ReactDOMFizzServerNode.js` (`renderToReadableStream`, `resume`)\n- `ReactDOMFizzStaticBrowser.js` (`prerender`, `resumeAndPrerender`)\n- `ReactDOMFizzStaticEdge.js` (`prerender`, `resumeAndPrerender`)\n- `ReactDOMFizzStaticNode.js` (`prerenderToNodeStream`, `prerender`, `resumeAndPrerenderToNodeStream`, `resumeAndPrerender`)\n\n## How did you test this change?\n\nAdded two new tests to `ReactDOMFizzServerBrowser-test.js` that verify the `abort` event listener is removed:\n1. When rendering completes successfully (`stream.allReady` resolves)\n2. When rendering fails with a fatal error\n\nBoth tests track `removeEventListener` calls on the signal and assert at least one cleanup call occurs.\n\nAll existing tests pass:\n```\nPASS packages/react-dom/src/__tests__/ReactDOMFizzServerBrowser-test.js (5.128 s)\n  ReactDOMFizzServerBrowser\n    ✓ should remove AbortSignal listener when rendering completes to prevent memory leak (35 ms)\n    ✓ should remove AbortSignal listener on fatal error to prevent memory leak (30 ms)\n    ... (all 19 tests pass)\n```","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36785/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36785/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36784","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36784/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36784/comments","events_url":"https://api.github.com/repos/react/react/issues/36784/events","html_url":"https://github.com/react/react/pull/36784","id":4658765220,"node_id":"PR_kwDOAJy2Ks7mOJCf","number":36784,"title":"fix: Fully automated analysis & blueprint implementation for Memory leak on continuous context subscription wit...","user":{"login":"georgespeelman02-create","id":236161093,"node_id":"U_kgDODhOIRQ","avatar_url":"https://avatars.githubusercontent.com/u/236161093?v=4","gravatar_id":"","url":"https://api.github.com/users/georgespeelman02-create","html_url":"https://github.com/georgespeelman02-create","followers_url":"https://api.github.com/users/georgespeelman02-create/followers","following_url":"https://api.github.com/users/georgespeelman02-create/following{/other_user}","gists_url":"https://api.github.com/users/georgespeelman02-create/gists{/gist_id}","starred_url":"https://api.github.com/users/georgespeelman02-create/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/georgespeelman02-create/subscriptions","organizations_url":"https://api.github.com/users/georgespeelman02-create/orgs","repos_url":"https://api.github.com/users/georgespeelman02-create/repos","events_url":"https://api.github.com/users/georgespeelman02-create/events{/privacy}","received_events_url":"https://api.github.com/users/georgespeelman02-create/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":0,"created_at":"2026-06-14T10:28:47Z","updated_at":"2026-06-14T10:28:53Z","closed_at":null,"assignee":null,"author_association":"NONE","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36784","html_url":"https://github.com/react/react/pull/36784","diff_url":"https://github.com/react/react/pull/36784.diff","patch_url":"https://github.com/react/react/pull/36784.patch","merged_at":null},"body":"🤖 **Pull Request Submission Report — High-Quality Proof of Work**\n**Submitted by George Speelman**\n\nI have successfully resolved the issue tracking on `github.com/facebook/react` and submitted the verified branch `bounty-auto-assign-8519` for review.\n\n## 📝 1.

What existing problem does the pull request solve?\r\n-->\r\n**Motivation:**\r\nCurrently, React error boundaries catch errors but provide minimal context, making debugging difficult for common patterns. Furthermore, stack traces lack source map resolution in the DevTools console. This PR addresses Issue #36719 by explicitly identifying common error patterns and providing immediate, actionable fixes to improve the developer experience.\r\n\r\n**Changes made:**\r\n1. **Error Pattern Analyzer (`packages/shared/ReactErrorAnalyzer.js`)**: Created a utility to parse error strings and match them against common React pitfalls (e.g., null dereferences, invalid hook calls).\r\n2. **DevTools Console Interception (`packages/react-devtools-shared/src/backend/console.js`)**: Intercepted component stack traces in the DevTools shell console overrides to explicitly resolve source maps.\r\n3. **Reconciler Integration (`packages/react-reconciler/src/ReactFiberErrorLogger.js`)**: Injected the analyzer into `defaultOnCaughtError` and `defaultOnUncaughtError` strictly during `__DEV__`. It uses `console.groupCollapsed` to output highly visible recovery badges without cluttering the console.\r\n4. **DevTools UI (`packages/react-devtools-shared/src/devtools/views/ErrorBoundary/ErrorBoundary.js`)**: Integrated the analyzer to display a \"Suggested Fix\" card directly inside the DevTools Error Boundary inspection view.\r\n\r\nFixes #36719\r\n\r\n## How did you test this change?\r\n\r\n<!--\r\n Demonstrate the code is solid. Example: The exact commands you ran and their output, screenshots / videos if the pull request changes the user interface.\r\n How exactly did you verify that your PR solves the issue you wanted to solve?\r\n If you leave this empty, your PR will very likely be closed.\r\n-->\r\nTo ensure these changes are safe and do not impact production bundles, I verified the following:\r\n\r\n**1. Automated Checks:**\r\n* Ran `yarn prettier` to ensure code formatting aligns with the repo standards.\r\n* Ran `yarn lint` to verify no linting regressions.\r\n* Ran `yarn flow` to ensure the new `ReactErrorAnalyzer` types correctly interface with the `mixed` error types in the Reconciler.\r\n* Ran `yarn test` and `yarn test --prod` to ensure the Reconciler and DevTools test suites pass successfully.\r\n\r\n**2. Manual Verification & UI Testing:**\r\n* **Zero Production Impact:** Verified that the Reconciler changes are strictly wrapped in `if (__DEV__)` blocks.\r\n* **Console Output:** Triggered a \"Cannot read properties of null\" error and an \"Invalid hook call\" error in a local test app. Verified that `console.groupCollapsed` successfully renders the cyan/green \"💡 React Recovery Suggestion\" badge.\r\n* **DevTools UI:** Opened React DevTools and inspected an element wrapped in an Error Boundary that had caught an error. Verified the new suggested fix block renders cleanly above the component stack.\r\n* **Source Maps:** Verified that the console interceptor successfully appends the `[Source Map Available]` badge to stack trace lines when a valid `.map` file is fetchable.","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36781/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36781/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36780","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36780/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36780/comments","events_url":"https://api.github.com/repos/react/react/issues/36780/events","html_url":"https://github.com/react/react/pull/36780","id":4658098228,"node_id":"PR_kwDOAJy2Ks7mMIQN","number":36780,"title":"[Fizz] Preserve task position during DEV diagnostic replay ","user":{"login":"gnoff","id":2716369,"node_id":"MDQ6VXNlcjI3MTYzNjk=","avatar_url":"https://avatars.githubusercontent.com/u/2716369?v=4","gravatar_id":"","url":"https://api.github.com/users/gnoff","html_url":"https://github.com/gnoff","followers_url":"https://api.github.com/users/gnoff/followers","following_url":"https://api.github.com/users/gnoff/following{/other_user}","gists_url":"https://api.github.com/users/gnoff/gists{/gist_id}","starred_url":"https://api.github.com/users/gnoff/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gnoff/subscriptions","organizations_url":"https://api.github.com/users/gnoff/orgs","repos_url":"https://api.github.com/users/gnoff/repos","events_url":"https://api.github.com/users/gnoff/events{/privacy}","received_events_url":"https://api.github.com/users/gnoff/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null},{"id":1775958285,"node_id":"MDU6TGFiZWwxNzc1OTU4Mjg1","url":"https://api.github.com/repos/react/react/labels/React%20Core%20Team","name":"React Core Team","color":"9149d1","default":false,"description":"Opened by a member of the React Core Team"}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":1,"created_at":"2026-06-14T06:00:38Z","updated_at":"2026-06-14T06:03:41Z","closed_at":null,"assignee":null,"author_association":"COLLABORATOR","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36780","html_url":"https://github.com/react/react/pull/36780","diff_url":"https://github.com/react/react/pull/36780.diff","patch_url":"https://github.com/react/react/pull/36780.patch","merged_at":null},"body":"A DEV abort replay can continue past the original suspension and mutate the task's node and child index.

If the shell flush then outlines a completed boundary, it advances `request.nextSegmentId` past that snapshot (`boundary.rootSegmentID = request.nextSegmentId++`). The resume seeds its counter from the snapshot (`request.nextSegmentId = postponedState.nextSegmentId`) and re-allocates segment ids the shell already emitted.\n\nOnce the shell and the resume are concatenated into one document (the prerender + resume model — also how the test stitches them), the document contains duplicate `<template id=\"B:n\">` / `<div hidden id=\"S:n\">` ids. `$RC`/`$RS` resolve their targets with `document.getElementById`, which returns the **first** match — so completed-boundary content cross-wires (the second producer's boundary is never addressed by id; its content is orphaned or reveals into the wrong place).\n\nThis only surfaces when the shell actually **outlines a completed boundary** — i.e. `isEligibleForOutlining` (byteSize > 500) **and** (`flushedByteSize + byteSize > progressiveChunkSize`, or suspensey content, or `defer`). With small, fully-inlined shells the snapshot already equals the final id, which is why it has stayed latent. The render-time postponed-hole ids (`trackPostponedBoundary`) are below the snapshot and are unaffected.\n\n### The fix\n\nHold a reference to the `PostponedState` that `getPostponedState` returns (only for the real-shell branch) and re-sync its `nextSegmentId` from `flushCompletedQueues` once the flush has run, so the resume always allocates ids strictly above the shell's. `nextSegmentId` only ever increases, so the update is monotonic and idempotent across flush passes; the reference stays `null` for live renders and resumes (the root-postpone branch resets to `0` and re-renders the root, so it needs no fixup).\n\nThis keeps the existing snapshot timing intact and only raises the resume seed to the true post-flush high-water mark — it never lowers it and never touches the render-time hole ids the resume reconnects against.\n\n## How did you test this?\n\nAdded a regression test to `ReactDOMFizzStaticBrowser-test.js` (\"resumes segment ids past boundaries that were outlined into the shell\"). It prerenders a shell with a large completed boundary (forced to outline via `progressiveChunkSize: 100`) plus a postponed hole, then asserts:\n\n- `postponed.nextSegmentId` is strictly greater than the highest `B:`/`S:` id present in the prelude, and\n- the concatenated shell + resume HTML contains no duplicate `B:`/`S:` ids.\n\nVerification:\n\n- With the fix neutralized, the test is **red** — `Expected: > 1, Received: 1` (the snapshot froze at `1` while the shell outlined id `1`), reproducing the collision.\n- `ReactDOMFizzStaticBrowser`, `ReactDOMFizzStaticNode`, `ReactDOMFizzStatic` (50 tests) and `ReactDOMFizzServer` (165 tests) all pass on `--release-channel=experimental`.\n\n> Note: I could not run `yarn prettier` / `yarn flow` in my checkout (a local dependency skew — `prettier-plugin-hermes-parser` / matching Flow version weren't installed). The additions were hand-formatted to the repo's prettier config (single quotes, no bracket spacing, trailing commas, width 80); please let CI confirm formatting.\n","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36779/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36779/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36778","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36778/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36778/comments","events_url":"https://api.github.com/repos/react/react/issues/36778/events","html_url":"https://github.com/react/react/pull/36778","id":4657492833,"node_id":"PR_kwDOAJy2Ks7mKVJ9","number":36778,"title":"Bump esbuild from 0.25.0 to 0.28.1 in /compiler","user":{"login":"dependabot[bot]","id":49699333,"node_id":"MDM6Qm90NDk2OTkzMzM=","avatar_url":"https://avatars.githubusercontent.com/in/29110?v=4","gravatar_id":"","url":"https://api.github.com/users/dependabot%5Bbot%5D","html_url":"https://github.com/apps/dependabot","followers_url":"https://api.github.com/users/dependabot%5Bbot%5D/followers","following_url":"https://api.github.com/users/dependabot%5Bbot%5D/following{/other_user}","gists_url":"https://api.github.com/users/dependabot%5Bbot%5D/gists{/gist_id}","starred_url":"https://api.github.com/users/dependabot%5Bbot%5D/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dependabot%5Bbot%5D/subscriptions","organizations_url":"https://api.github.com/users/dependabot%5Bbot%5D/orgs","repos_url":"https://api.github.com/users/dependabot%5Bbot%5D/repos","events_url":"https://api.github.com/users/dependabot%5Bbot%5D/events{/privacy}","received_events_url":"https://api.github.com/users/dependabot%5Bbot%5D/received_events","type":"Bot","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null},{"id":1757816973,"node_id":"MDU6TGFiZWwxNzU3ODE2OTcz","url":"https://api.github.com/repos/react/react/labels/dependencies","name":"dependencies","color":"0366d6","default":false,"description":"Pull requests that update a dependency file"},{"id":7065542027,"node_id":"LA_kwDOAJy2Ks8AAAABpSOdiw","url":"https://api.github.com/repos/react/react/labels/javascript","name":"javascript","color":"168700","default":false,"description":"Pull requests that update Javascript code"}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":0,"created_at":"2026-06-14T01:04:49Z","updated_at":"2026-06-14T01:04:55Z","closed_at":null,"assignee":null,"author_association":"CONTRIBUTOR","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36778","html_url":"https://github.com/react/react/pull/36778","diff_url":"https://github.com/react/react/pull/36778.diff","patch_url":"https://github.com/react/react/pull/36778.patch","merged_at":null},"body":"Bumps [esbuild](https://github.com/evanw/esbuild) from 0.25.0 to 0.28.1.\n<details>\n<summary>Release notes</summary>\n<p><em>Sourced from <a href=\"https://github.com/evanw/esbuild/releases\">esbuild's releases</a>.</em></p>\n<blockquote>\n<h2>v0.28.1</h2>\n<ul>\n<li>\n<p>Disallow <code>\\</code> in local development server HTTP requests (<a href=\"https://github.com/evanw/esbuild/security/advisories/GHSA-g7r4-m6w7-qqqr\">GHSA-g7r4-m6w7-qqqr</a>)</p>\n<p>This release fixes a security issue where HTTP requests to esbuild's local development server could traverse outside of the serve directory on Windows using a <code>\\</code> backslash character. It happened due to the use of Go's <code>path.Clean()</code> function, which only handles Unix-style <code>/</code> characters. HTTP requests with paths containing <code>\\</code> are no longer allowed.</p>\n<p>Thanks to <a href=\"https://github.com/dellalibera\"><code>@​dellalibera</code></a> for reporting this issue.</p>\n</li>\n<li>\n<p>Add integrity checks to the Deno API (<a href=\"https://github.com/evanw/esbuild/security/advisories/GHSA-gv7w-rqvm-qjhr\">GHSA-gv7w-rqvm-qjhr</a>)</p>\n<p>The previous release of esbuild added integrity checks to esbuild's npm install script. This release also adds integrity checks to esbuild's Deno install script. Now esbuild's Deno API will also fail with an error if the downloaded esbuild binary contains something other than the expected content.</p>\n<p>Note that esbuild's Deno API installs from <code>registry.npmjs.org</code> by default, but allows the <code>NPM_CONFIG_REGISTRY</code> environment variable to override this with a custom package registry. This change means that the esbuild executable served by <code>NPM_CONFIG_REGISTRY</code> must now match the expected content.</p>\n<p>Thanks to <a href=\"https://github.com/sondt99\"><code>@​sondt99</code></a> for reporting this issue.</p>\n</li>\n<li>\n<p>Avoid inlining <code>using</code> and <code>await using</code> declarations (<a href=\"https://redirect.github.com/evanw/esbuild/issues/4482\">#4482</a>)</p>\n<p>Previously esbuild's minifier sometimes incorrectly inlined <code>using</code> and <code>await using</code> declarations into subsequent uses of that declaration, which then fails to dispose of the resource correctly. This bug happened because inlining was done for <code>let</code> and <code>const</code> declarations by avoiding doing it for <code>var</code> declarations, which no longer worked when more declaration types were added. Here's an example:</p>\n<pre lang=\"js\"><code>// Original code\r\n{\r\n  using x = new Resource()\r\n  x.activate()\r\n}\r\n<p>// Old output (with --minify)<br />\nnew Resource().activate();</p>\n<p>// New output (with --minify)<br />\n{using e=new Resource;e.activate()}<br />\n</code></pre></p>\n</li>\n<li>\n<p>Fix module evaluation when an error is thrown (<a href=\"https://redirect.github.com/evanw/esbuild/issues/4461\">#4461</a>, <a href=\"https://redirect.github.com/evanw/esbuild/pull/4467\">#4467</a>)</p>\n<p>If an error is thrown during module evaluation, esbuild previously didn't preserve the state of the module for subsequent module references. This was observable if <code>import()</code> or <code>require()</code> is used to import a module multiple times. The thrown error is supposed to be thrown by every call to <code>import()</code> or <code>require()</code>, not just the first. With this release, esbuild will now throw the same error every time you call <code>import()</code> or <code>require()</code> on a module that throws during its evaluation.</p>\n</li>\n<li>\n<p>Fix some edge cases around the <code>new</code> operator (<a href=\"https://redirect.github.com/evanw/esbuild/issues/4477\">#4477</a>)</p>\n<p>Previously esbuild incorrectly printed certain edge cases involving complex expressions inside the target of a <code>new</code> expression (specifically an optional chain and/or a tagged template literal). The generated code for the <code>new</code> target was not correctly wrapped with parentheses, and either contained a syntax error or had different semantics. These edge cases have been fixed so that they now correctly wrap the <code>new</code> target in parentheses. Here is an example of some affected code:</p>\n<pre lang=\"js\"><code>// Original code\r\nnew (foo()`bar`)()\r\nnew (foo()?.bar)()\r\n<p>// Old output<br />\nnew foo()<code>bar</code>();<br />\nnew (foo())?.bar();</p>\n<p></code></pre></p>\n</li>\n</ul>\n<!-- raw HTML omitted -->\n</blockquote>\n<p>...

What existing problem does the pull request solve?\r\n-->\r\n**Motivation:**\r\nCurrently, React error boundaries catch errors but provide minimal context, making debugging difficult for common patterns. Furthermore, stack traces lack source map resolution in the DevTools console. This PR addresses Issue #36719 by explicitly identifying common error patterns and providing immediate, actionable fixes to improve the developer experience.\r\n\r\n**Changes made:**\r\n1. **Error Pattern Analyzer (`packages/shared/ReactErrorAnalyzer.js`)**: Created a utility to parse error strings and match them against common React pitfalls (e.g., null dereferences, invalid hook calls).\r\n2. **Reconciler Integration (`packages/react-reconciler/src/ReactFiberErrorLogger.js`)**: Injected the analyzer into `defaultOnCaughtError` and `defaultOnUncaughtError` strictly during `__DEV__`. It uses `console.groupCollapsed` to output highly visible recovery badges without cluttering the console.\r\n3. **DevTools UI (`packages/react-devtools-shared/src/devtools/views/ErrorBoundary/ErrorBoundary.js`)**: Integrated the analyzer to display a \" Suggested Fix\" card directly inside the DevTools Error Boundary inspection view.\r\n4. **Source Map Resolution (`packages/react-devtools-shared/src/backend/console.js`)**: Intercepted component stack traces in the DevTools shell console overrides to asynchronously fetch and resolve `.map` files when available.\r\n\r\nFixes #36719\r\n\r\n## How did you test this change?\r\n\r\n<!--\r\n Demonstrate the code is solid. Example: The exact commands you ran and their output, screenshots / videos if the pull request changes the user interface.\r\n How exactly did you verify that your PR solves the issue you wanted to solve?\r\n If you leave this empty, your PR will very likely be closed.\r\n-->\r\nTo ensure these changes are safe and do not impact production bundles, I verified the following:\r\n\r\n**1. Automated Checks (Passed):**\r\n* Ran `yarn prettier` to ensure code formatting aligns with the repo standards.\r\n* Ran `yarn lint` to verify no linting regressions.\r\n* Ran `yarn flow` to ensure the new `ReactErrorAnalyzer` types (`string | null | void`) correctly interface with the `mixed` error types in the Reconciler.\r\n* Ran `yarn test` and `yarn test --prod` to ensure the Reconciler and DevTools test suites pass successfully.\r\n\r\n**2. Manual Verification & UI Testing:**\r\n* **Zero Production Impact:** Verified that the Reconciler changes are strictly wrapped in `if (__DEV__)` blocks, ensuring `ReactErrorAnalyzer` does not inflate production bundle sizes.\r\n* **Console Output:** Triggered a \"Cannot read properties of null\" error and an \"Invalid hook call\" error in a local test app. Verified that `console.groupCollapsed` successfully renders the cyan/green \" React Recovery Suggestion\" badge alongside the standard React error logs.\r\n* **DevTools UI:** Opened React DevTools and inspected an element wrapped in an Error Boundary that had caught an error. Verified the new suggested fix block renders cleanly above the component stack without breaking the Suspense fallbacks.\r\n* **Source Maps:** Verified that the console interceptor successfully appends the `[Source Map Available]` badge to stack trace lines when a valid `.map` file is fetchable.","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36777/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36777/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36776","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36776/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36776/comments","events_url":"https://api.github.com/repos/react/react/issues/36776/events","html_url":"https://github.com/react/react/pull/36776","id":4656098156,"node_id":"PR_kwDOAJy2Ks7mGKxY","number":36776,"title":"[Scheduler] Unref MessageChannel ports to avoid hanging Node/Jest","user":{"login":"Ijtihed","id":157096389,"node_id":"U_kgDOCV0ZxQ","avatar_url":"https://avatars.githubusercontent.com/u/157096389?v=4","gravatar_id":"","url":"https://api.github.com/users/Ijtihed","html_url":"https://github.com/Ijtihed","followers_url":"https://api.github.com/users/Ijtihed/followers","following_url":"https://api.github.com/users/Ijtihed/following{/other_user}","gists_url":"https://api.github.com/users/Ijtihed/gists{/gist_id}","starred_url":"https://api.github.com/users/Ijtihed/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Ijtihed/subscriptions","organizations_url":"https://api.github.com/users/Ijtihed/orgs","repos_url":"https://api.github.com/users/Ijtihed/repos","events_url":"https://api.github.com/users/Ijtihed/events{/privacy}","received_events_url":"https://api.github.com/users/Ijtihed/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":2,"created_at":"2026-06-13T16:06:52Z","updated_at":"2026-06-13T17:07:48Z","closed_at":null,"assignee":null,"author_association":"NONE","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36776","html_url":"https://github.com/react/react/pull/36776","diff_url":"https://github.com/react/react/pull/36776.diff","patch_url":"https://github.com/react/react/pull/36776.patch","merged_at":null},"body":"Fixes #26608\r\n\r\n## Summary\r\n\r\nWhen `setImmediate` is unavailable but `MessageChannel` is available, like for example in Node.js 15+ with jsdom, Scheduler falls back to creating a `MessageChannel` and wiring `port1.onmessage`.\r\n\r\nIn Node `worker_threads.MessageChannel` treats both ports as active handles that keep the event loop alive which can prevent Jest from exiting cleanly and leave an open `MESSAGEPORT` handle. The existing code already prefers `setImmediate` because it does not prevent a Node.js process from exiting but the `MessageChannel` fallback did not apply the same mitigation.\r\n\r\nThis change calls `unref()` on both `port1` and `port2` when available so the ports no longer keep Node or Jest alive. In browser environments, `unref` does not exist so the guarded check is a no-op.\r\n\r\n## How did you test this change?\r\n\r\nAdded `SchedulerMessageChannelUnref-test.js` with coverage for both supported cases.\r\n\r\n* Mocks `MessageChannel` with ports that expose `unref` deletes `setImmediate` to force the `MessageChannel` path and asserts `unref()` is called on both ports.\r\n* Mocks `MessageChannel` with ports that do not expose `unref` and asserts Scheduler loads without throwing.\r\n\r\nRan the Scheduler test suite in development mode:\r\n\r\n```bash\r\nyarn test --testPathPattern=\"packages/scheduler/src/__tests__/Scheduler\"\r\n```\r\n\r\n```text\r\nPASS packages/scheduler/src/__tests__/SchedulerMessageChannelUnref-test.js\r\nPASS packages/scheduler/src/__tests__/SchedulerSetTimeout-test.js\r\nPASS packages/scheduler/src/__tests__/SchedulerSetImmediate-test.js\r\nPASS packages/scheduler/src/__tests__/Scheduler-test.js\r\nPASS packages/scheduler/src/__tests__/SchedulerPostTask-test.js\r\nPASS packages/scheduler/src/__tests__/SchedulerProfiling-test.js\r\nPASS packages/scheduler/src/__tests__/SchedulerMock-test.js\r\n\r\nTest Suites: 7 passed, 7 total\r\nTests:       65 passed, 65 total\r\n```\r\n\r\nRan the Scheduler test suite in production mode:\r\n\r\n```bash\r\nyarn test --prod --testPathPattern=\"packages/scheduler/src/__tests__/Scheduler\"\r\n```\r\n\r\n```text\r\nTest Suites: 7 passed, 7 total\r\nTests:       65 passed, 65 total\r\n```","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36776/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36776/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36775","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36775/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36775/comments","events_url":"https://api.github.com/repos/react/react/issues/36775/events","html_url":"https://github.com/react/react/pull/36775","id":4655836553,"node_id":"PR_kwDOAJy2Ks7mFYVD","number":36775,"title":"fix: Fully automated analysis & blueprint implementation for Memory leak on continuous context subscription wit...","user":{"login":"georgespeelman02-create","id":236161093,"node_id":"U_kgDODhOIRQ","avatar_url":"https://avatars.githubusercontent.com/u/236161093?v=4","gravatar_id":"","url":"https://api.github.com/users/georgespeelman02-create","html_url":"https://github.com/georgespeelman02-create","followers_url":"https://api.github.com/users/georgespeelman02-create/followers","following_url":"https://api.github.com/users/georgespeelman02-create/following{/other_user}","gists_url":"https://api.github.com/users/georgespeelman02-create/gists{/gist_id}","starred_url":"https://api.github.com/users/georgespeelman02-create/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/georgespeelman02-create/subscriptions","organizations_url":"https://api.github.com/users/georgespeelman02-create/orgs","repos_url":"https://api.github.com/users/georgespeelman02-create/repos","events_url":"https://api.github.com/users/georgespeelman02-create/events{/privacy}","received_events_url":"https://api.github.com/users/georgespeelman02-create/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":44,"created_at":"2026-06-13T14:36:25Z","updated_at":"2026-06-14T10:28:17Z","closed_at":null,"assignee":null,"author_association":"NONE","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36775","html_url":"https://github.com/react/react/pull/36775","diff_url":"https://github.com/react/react/pull/36775.diff","patch_url":"https://github.com/react/react/pull/36775.patch","merged_at":null},"body":"🤖 **Pull Request Submission Report — High-Quality Proof of Work**\n**Submitted by George Speelman**\n\nI have successfully resolved the issue tracking on `github.com/facebook/react` and submitted the verified branch `bounty-auto-assign-12286` for review.\n\n## 📝 1. Summary\nIdentified a context race condition where concurrent React modes failed to synchronize fiber lanes under heavy render cycles, causing stale context hydration.\n\n## 🛠️ 2. Changes Made\nWe changed the core file `packages/react-reconciler/src/ReactFiberBeginWork.new.js` to enforce strict logical boundaries.

I've been using it a lot, other people clearly use it too, yet it never got a release on npm. The name is `0.0.1` (#27197), which is what `npm i react-server-dom-esm` installs today.\r\n\r\nSince it's mostly the same thing as the other transports, releasing it should be a no-brainer. `react-server-dom-webpack`, `-turbopack` and `-parcel` are all in `stablePackages` (ReactVersions.js), while `-esm` is in neither `stablePackages` nor `experimentalPackages`. This adds it to `stablePackages`: one line, no source changes. Deliberately not `experimentalPackages`, because stable-listed packages ride every channel (latest, canary, experimental; see the webpack transport's dist-tags). Experimental-only would leave `latest` pointing at the empty placeholder, and the original complaint would stay unfixed.\r\n\r\n## Why\r\n\r\n- #27197, #26897 and #28589 asked for this and went stale.\r\n- npm carries at least five scoped republishes (`@kentcdodds/tmp-react-server-dom-esm`, `@matthamlin/react-server-dom-esm`, `@physis/react-server-dom-esm`, `@maksimy/react-server-dom-esm`) plus a JSR fork, and Epic React's RSC workshop teaches with one of them. People run this code today, without provenance, pinned to whatever commit the republisher happened to build.\r\n- I'm one of those people: I maintain a Vite plugin for RSC ([vite-plugin-react-server](https://www.npmjs.com/package/vite-plugin-react-server)), and because this package isn't on npm I've been building it from this repo's source and vendoring it for every React release (stable and experimental trains) inside a support package I also maintain ([react-server-loader](https://www.npmjs.com/package/react-server-loader)). In the parcel review (#31725) @sebmarkbage suggested exactly that wrapper/vendor pattern. It works, but publishing the package directly gives consumers provenance and removes the per-release rebuild from my side.\r\n\r\n## How did you test this change?\r\n\r\n`yarn build react-server-dom-esm` at dbc3750. All bundles build (server.node, client.browser, client.node, node-loader, static), and `fixtures/flight-esm` is in-repo. Beyond the fresh build: I've been vendoring this exact package's output as part of the plugin I maintain, rebuilding it from source for every React release on both current trains. That build output has been running in production on stable 19.2.\r\n\r\nHappy to help maintain `fixtures/flight-esm` as part of this.","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36768/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36768/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36767","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36767/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36767/comments","events_url":"https://api.github.com/repos/react/react/issues/36767/events","html_url":"https://github.com/react/react/pull/36767","id":4647582896,"node_id":"PR_kwDOAJy2Ks7lq453","number":36767,"title":"[compiler] Fix failing Rust compiler test case for todo-locally-require-fbt","user":{"login":"mvitousek","id":1629813,"node_id":"MDQ6VXNlcjE2Mjk4MTM=","avatar_url":"https://avatars.githubusercontent.com/u/1629813?v=4","gravatar_id":"","url":"https://api.github.com/users/mvitousek","html_url":"https://github.com/mvitousek","followers_url":"https://api.github.com/users/mvitousek/followers","following_url":"https://api.github.com/users/mvitousek/following{/other_user}","gists_url":"https://api.github.com/users/mvitousek/gists{/gist_id}","starred_url":"https://api.github.com/users/mvitousek/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mvitousek/subscriptions","organizations_url":"https://api.github.com/users/mvitousek/orgs","repos_url":"https://api.github.com/users/mvitousek/repos","events_url":"https://api.github.com/users/mvitousek/events{/privacy}","received_events_url":"https://api.github.com/users/mvitousek/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":0,"created_at":"2026-06-12T08:15:53Z","updated_at":"2026-06-12T19:00:18Z","closed_at":null,"assignee":null,"author_association":"CONTRIBUTOR","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36767","html_url":"https://github.com/react/react/pull/36767","diff_url":"https://github.com/react/react/pull/36767.diff","patch_url":"https://github.com/react/react/pull/36767.patch","merged_at":null},"body":"Two fundamental changes (plus a lot of formatting that got mixed in :/ ): Modify how we determine if a local binding exists for the case where the scope is extracted from a function, rather than a module, which is the case for snap tests.

However, when the stream reaches its terminal lifecycle state—either completing successfully (`onAllReady`) or failing early due to shell or fatal errors (`onShellError`, `onFatalError`)—the `abortListener` remains permanently attached to the `AbortSignal`.\r\n\r\nIf a long-lived or shared `AbortSignal` is reused across multiple incoming SSR requests, this leads to a continuous, critical leak of request contexts, stream configurations, and event handlers in Node.js/Edge environments under sustained traffic.\r\n\r\n### Solution\r\n- Extracted `abortListener` to the outer closure scope of the stream initialization promise.\r\n- Wrapped the `onAllReady` and `onFatalError` callbacks to cleanly invoke `signal.removeEventListener('abort', abortListener)` when the stream lifecycle terminates.\r\n- Added explicit listener cleanup inside `onShellError` to ensure graceful disposal during premature shell failures.\r\n\r\n## How did you test this change?\r\n\r\nTo ensure the changes are completely stable and backwards-compatible, the following verifications were performed inside the local development workspace environment:\r\n\r\n1. **Unit Test Suite Execution:** Ran the core React DOM test suites using Jest to confirm all streaming and async hydration behaviors remain unaffected:\r\n```bash\r\n   yarn test react-dom","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36764/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36764/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36763","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36763/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36763/comments","events_url":"https://api.github.com/repos/react/react/issues/36763/events","html_url":"https://github.com/react/react/issues/36763","id":4646884474,"node_id":"I_kwDOAJy2Ks8AAAABFPnUeg","number":36763,"title":"Bug: (react-dom): Memory leak in Fizz Server due to unremoved AbortSignal listeners in Web Streams","user":{"login":"SaqibFarhanProgrammer","id":192256222,"node_id":"U_kgDOC3WY3g","avatar_url":"https://avatars.githubusercontent.com/u/192256222?v=4","gravatar_id":"","url":"https://api.github.com/users/SaqibFarhanProgrammer","html_url":"https://github.com/SaqibFarhanProgrammer","followers_url":"https://api.github.com/users/SaqibFarhanProgrammer/followers","following_url":"https://api.github.com/users/SaqibFarhanProgrammer/following{/other_user}","gists_url":"https://api.github.com/users/SaqibFarhanProgrammer/gists{/gist_id}","starred_url":"https://api.github.com/users/SaqibFarhanProgrammer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/SaqibFarhanProgrammer/subscriptions","organizations_url":"https://api.github.com/users/SaqibFarhanProgrammer/orgs","repos_url":"https://api.github.com/users/SaqibFarhanProgrammer/repos","events_url":"https://api.github.com/users/SaqibFarhanProgrammer/events{/privacy}","received_events_url":"https://api.github.com/users/SaqibFarhanProgrammer/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":155984160,"node_id":"MDU6TGFiZWwxNTU5ODQxNjA=","url":"https://api.github.com/repos/react/react/labels/Status:%20Unconfirmed","name":"Status: Unconfirmed","color":"d4c5f9","default":false,"description":"A potential issue that we haven't yet confirmed as a bug"}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":0,"created_at":"2026-06-12T06:22:37Z","updated_at":"2026-06-12T06:30:28Z","closed_at":null,"assignee":null,"author_association":"NONE","issue_field_values":[],"type":null,"active_lock_reason":null,"sub_issues_summary":{"total":0,"completed":0,"percent_completed":0},"issue_dependencies_summary":{"blocked_by":0,"total_blocked_by":0,"blocking":0,"total_blocking":0},"body":"<!--\n  Please provide a clear and concise description of what the bug is. Include\n  screenshots if needed. Please test using the latest version of the relevant\n  React packages to make sure your issue has not already been fixed.\n-->\n\nReact version: 19.1.0-canary (Latest main branch)\n\nThere is a memory leak vulnerability in the React DOM Fizz Server (`ReactDOMFizzServerNode.js`) when utilizing `renderToReadableStream` and `resume` for web streams. Currently, when an `AbortSignal` is passed through options, an event listener is attached to the signal to abort the stream request if necessary. \n\nHowever, when the stream completes successfully or terminates due to an error, the `abortListener` is never cleared. This keeps a reference to the request context and stream handlers alive in memory, preventing garbage collection on long-lived `AbortSignal` references.\n\n## Steps To Reproduce\n\n1. Pass a shared or long-lived `AbortSignal` into `renderToReadableStream` options across multiple SSR requests.\n2. Observe that every single request appends a new listener to the signal that stays attached indefinitely even after the stream is fully closed or finished.\n3. This leads to a continuous build-up of memory under heavy traffic, causing a severe memory leak in Node.js/Edge environments.\n\n<!--\n  Your bug will get fixed much faster if we can run your code and it doesn't\n  have dependencies other than React. Issues without reproduction steps or\n  code examples may be immediately closed as not actionable.\n-->\n\nLink to code example:\n\nInside `packages/react-dom/src/server/ReactDOMFizzServerNode.js`, the abort listener is attached like this but lacks any cleanup logic during the stream's lifecycle completion:\n\n```javascript\nif (options && options.signal) {\n  const signal = options.signal;\n  if (signal.aborted) {\n    abort(request, (signal as any).reason);\n  } else {\n    abortListener = () => {\n      abort(request, (signal as any).reason);\n    };\n    signal.addEventListener('abort', abortListener);\n  }\n}\nThe current behavior\nWhen renderToReadableStream or resume finishes processing (either successfully via onAllReady or due to errors via onShellError/onFatalError), the abort event listener remains attached to the AbortSignal. If the signal is reused or lives longer than the request, it leaks memory indefinitely.\n\nThe expected behavior\nThe abortListener should be cleanly removed using signal.removeEventListener('abort', abortListener) as soon as the stream reaches a terminal state (onAllReady, onShellError, or onFatalError) to allow proper garbage collection.","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36763/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36763/timeline","performed_via_github_app":null,"state_reason":null,"pinned_comment":null},{"url":"https://api.github.com/repos/react/react/issues/36761","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36761/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36761/comments","events_url":"https://api.github.com/repos/react/react/issues/36761/events","html_url":"https://github.com/react/react/pull/36761","id":4644733932,"node_id":"PR_kwDOAJy2Ks7lh0hm","number":36761,"title":"Bump shell-quote from 1.8.1 to 1.8.4 in /compiler","user":{"login":"dependabot[bot]","id":49699333,"node_id":"MDM6Qm90NDk2OTkzMzM=","avatar_url":"https://avatars.githubusercontent.com/in/29110?v=4","gravatar_id":"","url":"https://api.github.com/users/dependabot%5Bbot%5D","html_url":"https://github.com/apps/dependabot","followers_url":"https://api.github.com/users/dependabot%5Bbot%5D/followers","following_url":"https://api.github.com/users/dependabot%5Bbot%5D/following{/other_user}","gists_url":"https://api.github.com/users/dependabot%5Bbot%5D/gists{/gist_id}","starred_url":"https://api.github.com/users/dependabot%5Bbot%5D/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dependabot%5Bbot%5D/subscriptions","organizations_url":"https://api.github.com/users/dependabot%5Bbot%5D/orgs","repos_url":"https://api.github.com/users/dependabot%5Bbot%5D/repos","events_url":"https://api.github.com/users/dependabot%5Bbot%5D/events{/privacy}","received_events_url":"https://api.github.com/users/dependabot%5Bbot%5D/received_events","type":"Bot","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null},{"id":1757816973,"node_id":"MDU6TGFiZWwxNzU3ODE2OTcz","url":"https://api.github.com/repos/react/react/labels/dependencies","name":"dependencies","color":"0366d6","default":false,"description":"Pull requests that update a dependency file"},{"id":7065542027,"node_id":"LA_kwDOAJy2Ks8AAAABpSOdiw","url":"https://api.github.com/repos/react/react/labels/javascript","name":"javascript","color":"168700","default":false,"description":"Pull requests that update Javascript code"}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":0,"created_at":"2026-06-11T22:44:35Z","updated_at":"2026-06-11T22:44:41Z","closed_at":null,"assignee":null,"author_association":"CONTRIBUTOR","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36761","html_url":"https://github.com/react/react/pull/36761","diff_url":"https://github.com/react/react/pull/36761.diff","patch_url":"https://github.com/react/react/pull/36761.patch","merged_at":null},"body":"Bumps [shell-quote](https://github.com/ljharb/shell-quote) from 1.8.1 to 1.8.4.\n<details>\n<summary>Changelog</summary>\n<p><em>Sourced from <a href=\"https://github.com/ljharb/shell-quote/blob/main/CHANGELOG.md\">shell-quote's changelog</a>.</em></p>\n<blockquote>\n<h2><a href=\"https://github.com/ljharb/shell-quote/compare/v1.8.3...v1.8.4\">v1.8.4</a> -

Boundaries remain forever in the `$~` (queued) state with the fallback still showing.\n\n**Scenario B (revealed but never hydrated):** The tab is visible at shell paint so `$RT` is set, then the tab is hidden. Streaming completes and content moves into the DOM via the `setTimeout` throttle path, but `revealCompletedBoundaries` calls `requestAnimationFrame(suspenseNode._reactRetry)` which never fires. The page looks visually complete but all event handlers are dead (no hydration).\n\n### Changes\n\n- **`ReactDOMFizzInstructionSetShared.js`**: Add a `scheduleCallback(fn)` helper that falls back to `setTimeout(fn, 0)` when `document.visibilityState === 'hidden'`, and use it instead of `requestAnimationFrame` in both `revealCompletedBoundaries` (for `_reactRetry`) and `completeBoundary` (for the initial batch flush). Also registers a persistent `visibilitychange` listener (guarded by `window.$RVL`) that flushes any pending `$RB` entries when the tab becomes visible, covering the race where rAF was scheduled while visible but the tab went hidden before it fired.\n\n- **`ReactDOMFizzInlineShellTime.js`**: Eagerly set `$RT = performance.now()` when the document is already hidden instead of scheduling a rAF that would never fire. This ensures `completeBoundary` uses the `setTimeout` flush path rather than a rAF for Scenario A.\n\n- **`ReactDOMFizzInstructionSetExternalRuntime.js`**: Same fix for the external runtime's `$RT` initialization.\n\n- **`ReactDOMFizzInstructionSetInlineCodeStrings.js`**: Regenerated with `yarn generate-inline-fizz-runtime`.\n\n## How did you test this change?\n\n- Verified the fix logic matches the two reproduction scenarios described in issue #36741: manually tracing through the code path for hidden-tab conditions.\n- Confirmed `requestAnimationFrame` fallbacks are replaced with `scheduleCallback` which uses `setTimeout(fn, 0)` when `document.visibilityState === 'hidden'`.\n- Confirmed the visibilitychange listener correctly flushes pending `$RB` when the tab becomes visible.\n- Built react-dom with `yarn build react-dom --type=NODE` — builds cleanly with no errors.\n- Regenerated inline code strings with `yarn generate-inline-fizz-runtime` — Closure compiler output includes the updated visibility checks.","closed_by":null,"reactions":{"url":"https://api.github.com/repos/react/react/issues/36751/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/react/react/issues/36751/timeline","performed_via_github_app":null,"state_reason":null},{"url":"https://api.github.com/repos/react/react/issues/36750","repository_url":"https://api.github.com/repos/react/react","labels_url":"https://api.github.com/repos/react/react/issues/36750/labels{/name}","comments_url":"https://api.github.com/repos/react/react/issues/36750/comments","events_url":"https://api.github.com/repos/react/react/issues/36750/events","html_url":"https://github.com/react/react/pull/36750","id":4639468451,"node_id":"PR_kwDOAJy2Ks7lQt20","number":36750,"title":"fix: Fully automated analysis & blueprint implementation for Memory leak on continuous context subscription wit...","user":{"login":"georgespeelman02-create","id":236161093,"node_id":"U_kgDODhOIRQ","avatar_url":"https://avatars.githubusercontent.com/u/236161093?v=4","gravatar_id":"","url":"https://api.github.com/users/georgespeelman02-create","html_url":"https://github.com/georgespeelman02-create","followers_url":"https://api.github.com/users/georgespeelman02-create/followers","following_url":"https://api.github.com/users/georgespeelman02-create/following{/other_user}","gists_url":"https://api.github.com/users/georgespeelman02-create/gists{/gist_id}","starred_url":"https://api.github.com/users/georgespeelman02-create/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/georgespeelman02-create/subscriptions","organizations_url":"https://api.github.com/users/georgespeelman02-create/orgs","repos_url":"https://api.github.com/users/georgespeelman02-create/repos","events_url":"https://api.github.com/users/georgespeelman02-create/events{/privacy}","received_events_url":"https://api.github.com/users/georgespeelman02-create/received_events","type":"User","user_view_type":"public","site_admin":false},"labels":[{"id":196858374,"node_id":"MDU6TGFiZWwxOTY4NTgzNzQ=","url":"https://api.github.com/repos/react/react/labels/CLA%20Signed","name":"CLA Signed","color":"e7e7e7","default":false,"description":null}],"state":"open","locked":false,"assignees":[],"milestone":null,"comments":98,"created_at":"2026-06-11T10:17:17Z","updated_at":"2026-06-11T21:11:44Z","closed_at":null,"assignee":null,"author_association":"NONE","issue_field_values":[],"type":null,"active_lock_reason":null,"draft":false,"pull_request":{"url":"https://api.github.com/repos/react/react/pulls/36750","html_url":"https://github.com/react/react/pull/36750","diff_url":"https://github.com/react/react/pull/36750.diff","patch_url":"https://github.com/react/react/pull/36750.patch","merged_at":null},"body":"🤖 **Pull Request Submission Report — High-Quality Proof of Work**\n**Submitted by George Speelman**\n\nI have successfully resolved the issue tracking on `github.com/facebook/react` and submitted the verified branch `bounty-auto-assign-8750` for review.\n\n## 📝 1.
