When a WebHTMLView has embedded attachments in it, the AXParent of those attachments is wrong. It usually points to the AXScrollView of the web area.
That's because there's been no way for WebCore to communicate that this attachment view should actually make believe that it's parent is within the WebCore AX tree.
We can fix that by overriding the AXParent in overriden attributes
