Summary AX: state changes of details/summary not announced by VoiceOver
Curtis Wilcox
Reported 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: https://cdpn.io/pen/debug/LYqYRMx 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 was made aware of this by EJ Mason: https://front-end.social/@codeability/111269806820815757

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