+        Prevent assertion/duplicate loads for non-deferred subtitute-data loads
+
+        https://bugs.webkit.org/show_bug.cgi?id=30879
+
+        MainResourceLoader uses the member m_initialRequest to store requests for future
+        deferred loads. When doing the actual load in handleDataLoadNow(), we therefore
+        have to clear this request so that subsequent entries into the loader will not
+        start yet another load.
+
+        This can happen as a result of a PageGroupLoadDeferrer going out of scope when
+        returning from Chrome::runJavaScriptAlert(), which calls setDeferredLoading(false),
+        but only in the case of using both substitute-data and non-deferred main resource
+        load together. That's why two new DRT functions were added:
+
+         * queueLoadHTMLString()
+         * setDeferMainResourceLoad()
+
+        The change adds DRT hooks for Mac, Win and Qt for these two functions. For Mac
+        and Win the hook uses new SPI in WebDataSource. For Qt a new static member was
+        added to the FrameLoaderClientQt and accessed though DumpRenderTreeSupportQt.

+
+        Test: fast/events/spatial-navigation/snav-zero-margin-content.html
+
+        Currently in WebCore::renderRectRelativeToRootDocument function, we are calling
+        RenderObject::absoluteClippedOverflowRect to obtain the rect boundary of a given
+        renderer/element. This method deals with outline, which is out of elements boundary.
+        It makes spatial navigation to fail on common sites like google.gom: "Web, Images, Map, etc"
+        are inaccessible.
+
+        Patch replaces RenderObject::absoluteClippedOverflowRect by Node::getRect,
+        which returns only the absolute bounding box rect of the Element.
