I like separating these out into another interface. So there's

// interface
class SaveCardBubbleController ...

and

// impl
class SaveCardBubbleControllerImpl : public SaveCardBubbleController, public
content::WebContentsObserver ...

and the view only sees SaveCardBubbleController

Sounds good. I'll do that.
