REGRESSION (r49394): Image load event fires before the document fragment is attached.

[Dimitri Glazkov (Google)]

What happens here is this:

* site loads some HTML via XHR
* then attempts to inject it into DOM
* as the HTML is being parsed, we encounter an image element with an onload handler
* image has already been loaded on the site, so we fire the onload handler immediately
* onload handler attempts to document.getElementById the element in the fragment.
* fragment isn't yet attached to DOM
* sadness ensues.
