[webkit-dev] Dummy Document in HTMLTreeBuilder::FragmentParsingContext

We use a dummy document there to match the processing model in the
spec. If we used the real document, we'd have to add a bunch of
branches to the HTMLTreeBuilder that aren't in the spec to get the
correct answer when parsing.
How is this document getting associated with a request object? That
seems like real bug. The dummy document has a NULL frame, which means
it shouldn't be kicking off any requests.
