Description Curtis Wilcox 2023-10-21 12:11:26 PDT 
When a <summary> element inside a <details> element is activated, VoiceOver does not announce the change in state ("collapsed", "expanded"). VoiceOver does announce the element's when focus moves to it.

Example:

I can reproduce the problem in Safari 17.0 and Technology Preview 181, on macOS 14.0 and 13.6. I can't reproduce the problem in Safari 16.5 on macOS 12.6.

I can still reproduce the problem using VoiceOver on macOS 14.3 with Safari 17.3 and Safari Technology Preview Release 187.
