testcase (requires extension for GC)

1. Temporarily install 'DOM Fuzz Lite' from
    https://www.squarefree.com/extensions/domFuzzLite.xpi
2. Load the testcase.

Result:
###!!! ASSERTION: No loadgroup for stylesheet; onload will fire early: 'loadGroup', file layout/style/Loader.cpp, line 1521

Preceded by the assertions in bug 605048.  Is this an expected consequence of bug 605048?
Not obviously, no.  How'd we end up with a document (and hence a CSSLoader) here at all?  Shouldn't removing the frame from the DOM have torn down the document inside?

Alternately, should the CSS loader make this assert a check-and-fail instead?
