Okay, so since this CL is changing the behavior on win as well, please double
check the all usage of Textfield and make sure it doesn't break the behavior,

I'll test all features carefully before landing this CL. It'll be great if you
guys can help test it as well :)

   virtual void ContentsChanged(Textfield* sender,
                                const string16& new_contents) = 0;
