From the standard USelectMenu. Click on it to open the combobox and scan using axe Devtools.

It will then fail the rule Certain ARIA roles must contain particular children


This is because the listbox should only contain children with the role option or group. https://www.w3.org/WAI/ARIA/apg/patterns/listbox/

Description

The dropdown in USelectMenu has the role listbox but it has children that do not have the role group or option. That is both the combobox input and the wrapping div:

<div tabindex="-1" data-slot="focusScope" class="flex flex-col min-h-0">.

So, it fails the axe-core rule "Certain ARIA roles must contain particular children".

Additional context

This is not an issue on Reka's Combobox, partially because the combobox input is not within the popup.

Logs

Start with the standard USelectMenu reproduction and inspect the opened combobox and listbox DOM while running axe DevTools. Trace the component entry point and surrounding focus-scope wrapper to identify why non-option children are inside the listbox. Done means the listbox structure follows the referenced ARIA pattern and the axe-core rule no longer reports an error.
