fix(combobox): only set aria-controls when open, fix reference id to list

[Barsnes]

DO NOT MERGE THIS TO MAIN

This has been synced in our next branch with PR ##2576

resolves #2552

This solves the issue by not adding aria-controls until the popup is visible (and in the DOM).
This also makes use of floating uis internal id, so the id is also correct.

Tested this branch with ARC toolkit and the error is no longer reported. I have not tested using a JAWS screen-reader though, as i dont have a license. 😅
(Edit: VoiceOver seems to work fine atleast)
