           Summary: REGRESSION (r49394): Image load event fires before the
                    document fragment is attached.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
               URL: http://klout.com/profile/stats/ghosttie/
        OS/Version: All
            Status: NEW
          Keywords: InChromiumBugs
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dglazkov at chromium.org

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.
