There's no reason for the default impl here to store this, right? The ash impl
can do the work instead.

Correct. I have changed the code according to your suggestion.
I didn't make SetController pure virtual to avoid implement them in two other
places. But if you think it is better to make it pure virtual, I will do the
change.

   const GURL default_url_;
 
   scoped_ptr<content::WebContents> keyboard_contents_;
