Actual Results

The ARIA attribute "aria-expanded" is inappropriately used on the "More action" element, (which becomes available on activating the "filter" button) in the main content area. As a result, screen reader users are communicated with inappropriate information.

Expected Results

Aria attribute should be appropriately used. Incorrect use of aria attributes should be avoided.

Remove the "aria-expanded" attribute from the "More actions" button in the page source.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
