Group listbox has inconsistent keyboard support

[jnurthen]

Example: https://w3c.github.io/aria-practices/examples/listbox/listbox-rearrangeable.html

Add one or more entries to the "Unimportant Features" listbox

• Note that Selecting an entry in the Unimportant Features list and pressing Enter moves it to the unimportant features list
• Note that Selecting an entry in the Important Features list and pressing Enter does NOT move it to the unimportant features list

These should be consistent. To be honest I don't mind which version gets implemented.

Thank you for the report James. We should either implement the Enter key behaviour for both listboxes (and document that behaviour). Or remove the Enter key behaviour from the one listbox.

Did you come across any of this behaviour in native components @jongund?

[JAWS-test]

On the page https://w3c.github.io/aria-practices/examples/listbox/listbox-rearrangeable.html there are two examples. In the first example only the right listbox can be operated with Enter, in the second only the left one.

@JAWS-test how is that different than what James said?

[JAWS-test]

@ZoeBijl My comment is a supplement, because the behavior described by James occurs only in the one example. In the other example it is the other way round.

Ahh! Thank you.
