Noted. Do you by any chance have a good reference (such as a "Short note") on why unhiding hidden elements (including elements in subtrees) doesn't work? The question arises quite often and developers try and try again. On
https://developer.paciellogroup.com/blog/2012/05/html5-accessibility-chops-hidden-and-aria-hidden/
it is explained, that aria-hidden="false" is not mapped, but I'm thinking of something like
<div aria-hidden="true">
<p aria-hidden="false">I am hidden from screen readers.</p>
</div>
