AI combobox: missing aria-activedescendant causes screen readers to announce "empty"

[Ovgodd]

Describe the bug
In the AI suggestion menu (combobox + listbox pattern), keyboard navigation works visually, but focus stays on the input and screen readers (NVDA / VoiceOver) announce “empty” while navigating with arrow keys.

Likely cause: the input does not update aria-activedescendant to the active option, so no option is announced.

Sr announce :

Ask anything...  édition  vide
vide
vide
vide
vide

To Reproduce

1. Open the AI menu (“Ask AI anything…”).
2. Type a few characters to show suggestions.
3. Use ↑ / ↓ to navigate the suggestions.
4. Observe: the active option changes visually, but the screen reader announces “empty” and does not read the active option.

I will handle This and propose a fix for it
