$(#document).closest('[foo]') throws error in IE

[cwolves]

Trying to access properties of what I think is a document fragment (nodeName === '#document' ) throws an error in IE:

Object doesn't support property or method 'getAttribute'

The code triggering this is $('iframe').contents().closest('[foo]')

Can you provide a simple reduced test case?

What is the use case for this? Closest is going to look up from the .contents() and that doesn't even seem useful.

the $('iframe').contents() piece is coming from a 3rd party plugin. I'm doing $node.closest('[foo]') for a separate purpose, I'm just getting a #document node.

nope, that's a different issue. Don't think it's iframes specifically, just the #document node

[timmywil]

@cwolves, I still wouldn't rule it out. .closest uses matchesSelector and calling matchesSelector on a document should be fine. ​http://jsfiddle.net/timmywil/qa29b/

Calling matchesSelector on an iframe document while trying to access an attribute could be a problem, but I will look into it more.

Fail silently if closest is somehow called on a document. Fixes #10726.
