So I guess if we go down this route we'll end up with ShadowRoot
checks in pre-insert. That seems fine.

Then we need to decide whether we want to expose ShadowRoot as
DocumentFragment in terms of nodeType and nodeName, or whether we just
treat those as legacy properties. I don't really care either way I
think, although cross-global instanceof checks are not guaranteed to
work (they do in Gecko at the moment, but I'm not sure that's the
right choice as cross-global instanceof does not work for Array and
