Wrong window object for iframes.

[mmariano]

I am assigning events to an iframe or svg from the parent window and hammerjs is using the parent window object when adding addEventListeners(). If you could instead get the element.ownerDocument and then the window object from the document that would help solve this problem.

What's the browser support of that property? I didn't know of its existence!

Here is how I have done it in production for a long time.

var doc = element.ownerDocument;
var win = (doc.defaultView || doc.parentWindow);

That works on iframes and svg 's and supports IE.

I think that you have to patch it again, because with that code you cannot use window as element, so probably it's best if you do:

var doc = element.ownerDocument || element;

So if element = window, everything works again. Anyway this is just a suggestion, use the best method you want.
