Not sure that we want to auto focus Ok button here.
Originally focus is on user images list so user could use keyboard to select
those, then press Enter to confirm selection. Then press Enter one more time to
close screen.

Done.

       okButton.addEventListener('click', this.acceptImage_.bind(this));
       return [okButton];
     },
