Details
Steps to reproduce:
- Load
data:text/html,<div role='listbox'><div role='group'><div role='option'>item</div></div></div> - Examine the accessibility tree in XCode's accessibility inspector
Expected results: the div with the group role would be present in the accessibility tree.
Actual results: Only the listbox and option are in the accessibility tree.
This problem doesn't appear in Linux, where the group-role div is exposed with ROLE_PANEL as expected.

S3 because this probably impacts reporting of groups where the group is labelled with VO. I also suspect <optgroup> might be broken, since that uses role="group", but I'm not sure.

Morgan, does your recent work on lists have any relevance here?

This still appears to be broken; the tree structure is: listbox > option
Safari's tree structure is: listbox > group > option

Right... but I thought there was some weird thing where you had to flatten groups in lists on Mac in order for them to be valid? Or am I misunderstanding?

Oh! Sorry I thought you were asking if it was related --> if it fixed this issue :)
Yes, I worked on this bug which had to do with exposing options inside of groups as selected or non-selected. VoiceOver wants listboxes to expose a set of selected children via AXSelectedChildren (really, this is a subset of all descendants, not just direct children). Prior to the patch at that bug, if a listbox had direct children with gecko role=grouping, we exposed the descendants of these groups as selectable, which is to-spec. Some gecko roles (which are not explicitly role=grouping) translate to AXRole = AXGroup and are valid to use as inner-groups in listboxes. When those AXGroup nodes were direct children of a listbox, we never traversed them / exposed their children as selectable. Post-patch, they are selectable becuase we check for AXRole = AXGroup rather than gecko role = grouping.
If the group accessibles mentioned in this bug are exposed in the gecko tree but not the mac tree, they're likely removed in our ignore child functions which we should fix
