Current behavior 😯

Autocompletes implemented with useAutocomplete do not highlight the options presented in the popper when presented. Additionally, when the user attempts to select an option by using the up or down arrow key, the selected row is not highlighted.

Key navigation is functional, in that the user is able to navigate to an option, press enter, and select it, but there is no visual feedback to let them know which option they’ve selected.

See the MUI v5 Autocomplete Demo

Expected behavior 🤔

The options should be highlighted when hovered and when the user uses the up or down arrow key while the popper is presented.

See the MUI v4 Autocomplete Demo

Steps to reproduce 🕹

Steps (see this codesandbox):

1. Focus the autocomplete field by pressing the tab key
2. Press the down arrow key to present the options
3. Hover over any of the presented options and observe that they do not highlight
4. Press the down arrow several times until the popper presenting the options scrolls a bit
5. Press the enter key and whichever option you’ve navigated to will be added as a selected option

Context 🔦

I have updated a MUI v4 app to v5 and noticed the referenced deficiencies in our autocompletes.
