Element path: .acd-toolbar-choicePicker:nth-child(3) > .ms-ctrl-dropdown[role="combobox"][aria-haspopup="listbox"]

Snippet: div tabindex="0" class="ms-ctrl ms-ctrl-dropdown" aria-labelledby="6e964434-5ed9-4dad-adad-536057b036ff 3101f8ff-491c-4653-b5e0-d8a8ab09c810" role="combobox" aria-haspopup="listbox" aria-expanded="true"

How to fix:
Fix any of the following:
Required ARIA attribute not present: aria-controls

User Experience:
When an element with an ARIA role requires specific child roles but they are missing, it can lead to accessibility issues for users who rely on assistive technologies (AT) like screen readers. The screen reader may not announce the element correctly, leading to confusion about its purpose. Users may miss interactive child elements because the parent role does not expose them properly.
