I just have concern that is it possible to implement it via less code
change. Because it seems to be a very simple function to pop an iframe window.
Not sure why it would involve so many code change. But I am not frontend
expert, I may be wrong on this. Wait for other frontend expert for more
comments. \cc @prabhjyotsingh ---
