I'm going to remove this FIXME in my next patchset--I looked at this more
closely, and it seems fine.

     LocalFrame* frame = m_frame->loader().findFrameForNavigation(nullAtom, callingWindow->document());
     if (!frame)
         return;
-    frame->domWindow()->setLocation(url, callingWindow, enteredWindow);
+    // FIXME: setLocation() probably belongs on DOMWindow, since you can trigger
+    // navigations across different origins.
+    frame->localDOMWindow()->setLocation(url, callingWindow, enteredWindow);
 }
