$( html, ownerDocument ) causes "createDocumentFragment is not a function" error

[scribu]

I am trying to create an element inside an iframe, like so:

var $iframe = $('iframe').contents(),
    $el = $('<div>', $iframe);

The second line causes an error in Firefox 3.6 and Chromium:

b.createDocumentFragment is not a function

jquery.min.js (line 120)

I have also tried $('<div>', $iframe.get()) and got the same result.

For some reason, the iframe Document object does not have that function.

I should note that the iframe is from the same domain.

I can call $iframe.find('body').prepend('foo'); just fine.

Found out that this works:

var $iframe = $('iframe').contents(),
    $el = $('<div>', $iframe.get(0));

Maybe providing an example in the ​documentation would help others that are stumbling into this.
