patch
it looks like your general approach is to try to invalidate tree role usage after the role has been assigned.
i think instead we should take the approach like AccessibilityList where AXObjectCache will make a new element t(AccessibilityTree.cpp) where we can override determineAccessibilityRole() to look at the children and change the role depending on what we need do that
that way we don't have to worry about missing any cases where tree role still peeks through and we don't have to pollute AccessibilityObject with methods that don't apply to all objects</pre>
