iFrame input detection to activate Vue-Keyboard

[thepepperone]

Hi there! I've used your library for a time now. And I must say this is a very great resource.
However, I'd like to, perhaps, request to add this as a feature:

Input detection and binding on embedded items like iframe, object, embed, webview and the like.

There could be a lot of instances with which apps would embed these type of features in their sites, especially on forms embedded on frames.

I found a similar case done using jquery but still want to know how to do this in vue, especially in binding the keyboard to all form inputs.
