This issue started with the latest Safari version 18.4. Hidden divs with `aria-labelledby` on them are having their names announced when accessed with the virtual cursor. The content within them is not being announced. In my case, this was noticeable on a div with `role="dialog"` since they have names, but I have created a reduced test case isolating the issue to just `hidden` and `aria-labelledby`. This was not the case in Safari 18.3 and it is also not happening on Chrome. https://codepen.io/hidanielle/full/MYYEQbQ For our use, this is quite a disruptive change.

Thanks for the minimal reproduction! Started working on this and found a fix I think is right, but it causes a different test failure I need to investigate. Attaching a WIP patch for myself to come back to.
