        <rdar://problem/4609195> Help Viewer loads empty window
        (not getting didFailLoadingWithError: callback)

        Call super's didFailWithError before _receivedMainResourceError
        because _receivedMainResourceError will cause the datasource's
        frame to be set to nil before the didFailLoadingWithError delegate
        callback is sent. (This order is needed now that WebDataSource does
        not hold on to the WebView; it uses the WebFrame to get to the WebView.
        If the WebFrame is nil we can't get to the WebView's resource load delegate.)

        * WebView/WebMainResourceLoader.m:
        (-[WebMainResourceLoader receivedError:]):
