Can you be clearer about "any methods are called to |bubble_view| without any
checks"? Do you mean |bubble_view| may be already destroyed, so any methods
called to |bubble_view| should be made with check?

removed the sentence of 'any methods...', I don't have enough literal sense to
write it, and 'may be already destroyed' would be good enough.

   virtual void HideBubbleWithView(const views::TrayBubbleView* bubble_view) = 0;
 
   // Called by the bubble wrapper when a click event occurs outside the bubble.
