Bug report

Current behavior

A disabled Autocomplete Item can be focused/highlighted using keyboard and pointer events and ends up with the data-highlighted attribute.

<Autocomplete.Item value="test" disabled>
   Test
</Autocomplete.Item>

Expected behavior

The disabled items should not be interactive and shouldn't have data-highlighted attribute.

Disabled items are intentionally focusable when disabled, but they should not be highlightable
