tested in Safari 9.1 
noted that summary has subrole of AXsummary and now identified as group, no indication it is interactive or of collapsed/expanded state.

Possibly needs to be duped out to bug 131111

Hi,
I have a question summary role on Mac.
From the spec, https://www.w3.org/TR/html-aam-1.0/#el-summary, it should be mapped to AXDisclosureTriangle but I found WebKit assigns AXButton to role for summary.

I tried to change it to AXDisclosureTriangle at createAccessibilityRoleMap() in WebAccessibilityObjectWrapperMac.mm and expanded or collapsed states were not updated with AXDisclosureTriangle role.

It seems Mac doesn't support expanded or collapsed state with AXDisclosureTriangle.
Could you check it?
Thanks,

Any update on this? Still present on iOS Safari 16.5 + VoiceOver. 

I consider this a pretty severe bug. When encountering a details/summary element, VO does not announce any kind of role, state, or any indication that the element can be interacted with. Many VO users will be blocked from the contents within if they don’t happen to guess that it can be expanded.
