Details

Some AccGroupInfo functionality fails to account for the possibility of intervening generic accessibles in the tree, particularly with compound ARIA widgets like tree + treeitems, or list + listitems. The functions that need to take this into account are:

  • FirstItemOf
  • NextItemTo
  • TotalItemCount

TotalItemCount uses FirstItemOf, and is called by Attributes/NativeAttributes to determine the value of the "child-item-count" attribute. FirstItemOf and NextItemTo are used by the ItemIterator, which is used by RelationByType implementations (for NODE_PARENT_OF).

Rather than assume that children and previous-index siblings are true siblings, we should instead do a tree walk to find siblings. An example of this work can be found in Bug 995064.
