Is it ok to ignore a case where editableRoot->deprecatedShadowAncestorNode()
returns editableRoot?

While making the patch i thought it was safe, but to be on the safe side i'll
add the check, so that it will also handle the above case.

 
     if (!editableRoot->getAttributeEventListener(EventTypeNames::webkitBeforeTextInserted) &&
         // FIXME: Remove these checks once textareas and textfields actually register an event handler.
         !(shadowAncestorNode && shadowAncestorNode->renderer() && shadowAncestorNode->renderer()->isTextControl()) &&
         editableRoot->rendererIsRichlyEditable()) {
         removeInterchangeNodes(m_fragment.get());
         return;
     }
 
     RefPtrWillBeRawPtr<Element> holder = insertFragmentForTestRendering(editableRoot.get());
