Steps to reproduce
Inspect the blue <div> above.
Switch to the Style side panel.
Click on the value of the background property to start inline editing.
Enter a value of "#9af ", and press up/down randomly with different selections. ⇒ The value and selection should match current behavior
Enter the following values, press up/down randomly with the cursor at random positions, and verify that the resulting value and selection matches current behavior:
"#9af "
"rgba(1,3, 9,0)"
"hsla(3,30%,9%,0"
Expected Results
If should be possible to in-/decrement different parts of colors,
in different amounts depending on Ctrl or
Shift or no modifier being pressed together
with Up/Down.
When several hex colors are selected, all of them should be in-/decremented.
