Won’t we get a warning because we are not using navigationID here?

Do we have a checked version of this cast? Should we?

Seems like coreFrame should return a reference, not a pointer.

I don't think we enable that warning.

We're sure that all document loaders are created by WebKit so I don't think we do.

I think the member variable backing coreFrame can end up being nulled out.
