Accessibility: Items not read aloud

[UltimateGG]

At least with ChromeVox: Using arrow keys does not announce the highlighted value. https://www.w3.org/WAI/ARIA/apg/patterns/combobox/examples/combobox-select-only/

I cannot figure out why, compared html to the WAI page's combobox, they look the same.

The issue is value not being in the dependency array for the useMemo of selectedItemId: https://github.com/pacocoursey/cmdk/blob/13f11c4f918cb4f7eb6254b4087a9cc83928b503/cmdk/src/index.tsx#L790C1-L790C9

I'd make a pull request but there is still some problems:

• To read it must have the element focused with the aria-activedescendant attribute
• If there is no Command.Input there is no focused element with activedescendant
• If an item is clicked the input is no longer focused
• The query for a selected item uses encodeURIComponent - Even on the demo website this breaks as spaces get "%20"'d and it thinks nothing is selected
