Reduced testcase

Take an element such as this one:

<div>
    <div id=foo></div>
</div>

If you call `.children.foo` on this element when it's not yet in the DOM tree, you'll get null, while the same code once the element is rooted in the DOM tree gets a reference to the <div id=foo> element.

This is only failing in WebKit nightlies and works fine on Safari 6.0.5.
