Why is this virtual?  No subclass overrides it AFAICT.

[Pritam Nikam, 2014/12/23 06:22:29]

Done.

Kept as non-virtual protected method (called from static functions from
|ZoomBubbleView::ShowBubble| & |ManagePasswordsBubbleView::ShowBubble|).

+
+  // Closes the bubble.
+  virtual void Close();
+
+ private:
+  // Used to register for fullscreen change notifications.
+  content::NotificationRegistrar registrar_;

+  DISALLOW_COPY_AND_ASSIGN(ManagedFullScreenBubbleDelegateView);
