In general I think we try to order these in the same order as the class they
come from. In this case it would be after OnMouseExited.

Done.

   virtual bool OnMousePressed(const views::MouseEvent& event) OVERRIDE;
   virtual void OnMouseReleased(const views::MouseEvent& event) OVERRIDE;
   virtual void OnMouseCaptureLost() OVERRIDE;
