- fix <rdar://problem/6990938> REGRESSION (r42787): After showing and
          hiding the Find banner, the WebHTMLView's height is not restored

        * WebView/WebFrameView.mm:
        (-[WebFrameView setFrameSize:]): Mark the FrameView for layout when the
        WebFrameView's size changes.
        * WebView/WebView.mm:
        (-[WebView setFrameSize:]): Left the resize logic here, but only for
        the single view model.
