Current Behavior

Tag picker is always empty in screen readers. Bellow is a copy of what NVDA is announcing during the interaction of focusing the tag picker, pressing a, pressing enter. (selecting the first employee from the list)

Text in bold is the exact same, so for aria the picker is always blank.

Expected Behavior

Bellow is how it used to work on fluent v8, it was still a bad experience because it announces blank but at least it had an aria-describedby property to the list inside the picker so it would allow the user to know that the current picker is not empty.
