Make inert subtrees and inert attr work for accessibility. Follow-up to these: http://webkit.org/b/110952 http://webkit.org/b/112085 inert elements should be removed from the accessibility tree
… or whatever falls out of this W3C mapping discussion. https://www.w3.org/Bugs/Public/show_bug.cgi?id=23350
Looks like the resolution was to map @inert to aria-hidden, and consider @aria-inert for a later version of ARIA. PFWG-ISSUE-623, currently on ARIA 1.1. https://www.w3.org/WAI/PF/Group/track/issues/623 One thing to consider is that the <dialog> behavior in HTML5 allows ancestor elements of the dialog to be inert, which m ay not map directly to @aria-hidden. In other words, what does it mean to have <dialog (not inert) aria-hidden="false"> element inside an ancestor <div inert (aria-hidden="true")>?
