Should we try to avoid this > duplicate update somehow? Yes, we should actually call postPlatformNotification instead. This made apparent the need to also update the target element when it is different from the original element. > > > Source/WebCore/accessibility/AXObjectCache.cpp:1896 > > + // NOtify active descendant changes only for the focused element. > > Typo here, capital O in "NOtify" Fixed in latest patch.
