Shall we have this ASSERT in oilpan builds as well?]

[Mads Ager (chromium), 2014/04/24 10:57:36]

I don't think we can. If this element dies at the same time as the document it
might still be registered as a pending resource with the document. However, that
doesn't matter because the document is also dead and we don't have to clear it
out.
