worried that this might populate tabChildren for elements not expected to have any... maybe we can change this to

if (role != TabList)
   return

> Source/WebCore/accessibility/isolatedtree/AXIsolatedTreeNode.cpp:696
> +Vector<RefPtr<Range>> AXIsolatedObject::findTextRanges(AccessibilitySearchTextCriteria const& criteria) const

what's the implication of returning a Range from the main thread to a secondary thread?

> Tools/WebKitTestRunner/InjectedBundle/AccessibilityController.cpp:101
>              m_semaphore.signal();

can you rename execute to something that is more meaningful in explaining that it will dispatch to the main thread

> Tools/WebKitTestRunner/InjectedBundle/AccessibilityController.cpp:104
> +        CFRunLoopRunInMode(kCFRunLoopDefaultMode, .25, false);

put a comment why we need to spin the run loop

This function is only used in the wrapper and will be always be executed inside a block dispatched to the main thread. You are right, it won't work if we return this value outside the main thread, but that is not happening.

Renamed it executeOnAXThreadIfPossible.

feel like we should assert main thread in this getter
