I don't understand this TODO. What's your followup plan?

[mustaq, 2017/04/26 18:12:48]

These were TODO for this CL. Done: moved them to non-overridden methods below.
Same in *Local*.h .

+  void InitializeCoreFrame(Page&, FrameOwner*, const AtomicString& name);
+  RemoteFrame* GetFrame() const { return frame_.Get(); }
 
   void SetCoreFrame(RemoteFrame*);
