Description Charlie 2022-11-04 17:26:06 PDT 
VoiceOver on iOS 15-16 will not read the role or state of a <details> and <summary> html element. 

To recreate:

Given that I am on a web page with a details/summary element: 
1. Activate VoiceOver in iOS 
2. Swipe to move focus to the summary 
3. Notice that the state/role of the element is not read 
4. Double tap to expand or collapse the details 
5. Notice that the state/role of the element is not read 

In previous versions, Voiceover would at least read the state (But not necessarily a role). 

You can see example videos of the proper behavior with working examples in previous versions of iOS.

This is similar to https://bugs.webkit.org/show_bug.cgi?id=241401 which is specific to iOS 16.

This is a blocking defect for anyone using VoiceOver.
