        This tab-to-links stuff has been in shaky condition ever since AppKit futzed with
        tabbing behavior in Tiger to add support for including the toolbar in the key loop.
        I made some changes months ago to compensate for that, but some cases, such as this
        one, still weren't fixed.

        * WebCoreSupport.subproj/WebBridge.m:
        (-[WebBridge _nextKeyViewOutsideWebFrameViewsWithValidityCheck:]):
        new bottleneck method, extracted from nextKeyViewOutsideWebFrameViews; handles
        nextKeyView or nextValidKeyView depending on parameter.
        (-[WebBridge nextKeyViewOutsideWebFrameViews]):
        now calls extracted method
        (-[WebBridge nextValidKeyViewOutsideWebFrameViews]):
        new method, calls new bottleneck method

        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView nextValidKeyView]):
        when we're stuck at the end of a nextKeyView chain inside a nexted frame, use
        nextValidKeyViewOutsideWebFrameViews. Make sure we don't end up looking inside
        the web frame views while doing this.
