REGRESSION: XMLHttpRequest::didFinishLoading() should immediately return if the request has already been aborted</p>
<p>If a frame has an active XMLHttpRequest that is still receiving data, and that frame is destroyed<br>
(or its load is otherwise stopped) the XMLHttpRequest gets an abort call then a didFinishedLoading call.</p>
<p>That didFinishedLoading() call should immediately exit and not update the object's state or do any 
other notifications.</p>
