I have the same problem. I don’t know when it appeared; it seems like it happened on its own, without any changes. Console error:
/#/accounts/index?return_module=Accounts&return_action=DetailView:1 Blocked aria-hidden on an element because its descendant retained focus. The focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at Accessible Rich Internet Applications (WAI-ARIA) 1.3.
Element with focus: input
Ancestor with aria-hidden: <input type=​"checkbox" aria-hidden=​"true">​
