Actual Results

ARIA attribute such as "aria-haspopup" is used to define the "Switch Report" and "board" expand/collapse buttons. As a result, screen reader users might get confused when assistive technology users will announce toggle and expand/collapse state for the same element.

Expected Results

Remove aria-haspopup attribute from the <button> elements.

Code Snippet

<button id="subnav-trigger-report" class="subnavigator-trigger aui-button aui-dropdown2-trigger" role="button" aria-label="Switch report" resolved="" aria-controls="subnav-opts-report" aria-expanded="false">Switch report</button>

Workaround

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