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.
