This looks great, but please move it to AXNodeObject.

In general, AXObject is supposed to contain logic that applies to all AX
objects, AXNodeObject should handle things that depend on it being a DOM node,
and AXRenderObject for things that may also depend on its RenderObject or
exactly how it's laid out on the screen.

Put an empty implementation here and override it in AXNodeObject.
