Describe your issue

I was just testing ComboBox with Voice over on Mac. And in safari it does not announce the options as I go through them. It can be reproduced directly on https://headlessui.com/vue/combobox using Safari on Mac.

I was comparing behaviour to https://react-spectrum.adobe.com/react-aria/ComboBox.html and https://www.w3.org/WAI/ARIA/apg/patterns/combobox/examples/combobox-autocomplete-list/ which announce it correctly and in the same way.

Additional difference I noticed that headlessui always automatically selects first item, without user pressing key down, which is different behaviour from the examples above - that was intentional choice, right? There seems to be some flexibility in specification.
