aria-expanded for tabs (https://jqueryui.com/tabs/)

[getaccessibility]

Aria-expanded is used for the

element with role="tab"
As per the ARIA specifications, aria-expanded is not supported for role tab. Since aria-selected conveys which tab is currently selected, aria-expanded must be removed from the widget.

Thanks for the report. Does the issue you describe exist when jQuery UI 1.12.1 is used or only with jQuery UI 1.13.0 or newer?

[getaccessibility]

Thanks for looking into it. Yes, the issue is observed in the latest jQuery UI 1.13 + version as well.

My question was whether it is observed in both 1.12.1 and 1.13.x or just in the latter one?

[getaccessibility]

Yes, it is observed in both 1.12.1 and 1.13 versions.

Since the issue is already in 1.12, given limited team resources it's not likely to be fixed by the UI team; see the project status at https://blog.jqueryui.com/2021/10/jquery-maintainers-update-and-transition-jquery-ui-as-part-of-overall-modernization-efforts/. PRs are welcome if they're not too complex.
