The “ARIA Hidden Focusable Content Check” evaluates whether all elements with aria-hidden="true" contain focusable or interactive content, such as buttons, links, or inputs.
Example outcome
I haven’t found any elements with the aria-hidden attribute that have focusable content.
Impact
Visual Impairments: A user may tab into a button or link that screen readers don’t announce, leaving them stuck or unaware of what’s happening.
Motor Impairments: People with motor impairments could land on a control that seems broken or unresponsive.
Cognitive Disabilities: Inconsistent or “ghost” interactions (that appear but aren’t announced) can confuse and frustrate.
Fixes
To address inappropriately focusable hidden content:
Locate the element that contains aria-hidden="true".
If that’s appropriate, remove focusable children from hidden containers.
If the children element(s) are interactable, remove the aria-hidden="true" attribute.
Finally, is most suitable, you can also disable the focusable element while it is hidden from assistive tech.
