[combo-box] Issues with selected item announcements in VoiceOver [1 day]

[web-padawan]

Problem

This is a follow-up from #2745 which works fine in NVDA, but not 100% in VoiceOver:

1. VoiceOver on Safari seems to require using live region because aria-activedescendant is not announced there, which is mentioned in React Aria.
2. VoiceOver on Chrome produces 2 subsequent announcements on Arrow Up & Arrow Down keys. First, the item is announced correctly with suffix e.g. selected (1 of 200), then only the text is announced.

Proposed solution

Check if this problem exists in other combo-box implementations and find a workaround, if possible.

Note

Checked the Lion combo-box and the second problem happens there as well.

This also happens in ARIA example, which makes me think it's a VoiceOver bug / limitation:

Same as above, happens in Safari for ARIA example as well. I don't think we can fix this 🤷‍♂️
