Nit: We might want to note why we'd want to move focus back to the textfield on
any events to begin with.

As discussed, I'm removing this workaround added for http://crbug.com/524373,
which no longer repros anyway. There's no reason to explicitly change focus.

+      if (!event.IsKeyEvent())
         find_text_->RequestFocus();
-      }
       break;

     default:
       NOTREACHED() << "Unknown button";
