280055 - Cannot walk into accessible tree for 2nd tab

Status: RESOLVED FIXED

(Firefox :: Disability Access, defect, P1)

Description

[Aaron Leventhal]

Using accessible explorer or inspect returns incorrect results when looking for
the object under the mouse pointer. This is because AccessibleObjectFromPoint
returns objects for the contents of the first tab.

This reminds me of fix to a similar bug for Seamonkey, although I don't remember
what the fix was.

Attachment: I would put this into nsViewManager::GetRectVisibility but I'd be concerned about perf regressions on UpdateView()

Although .. what about z-order?

To make this work right, you might have to call BuildDisplayList or something
like  that to get a list of the views under the point, sorted by z-order, the
way that nsViewManager::HandleEvent does.

I'll file a separate bug on that.
