Subject: [PATCH] Fix IDL definition of `LoadDocumentCallback`

Dictionary arguments cannot be nullable in Web IDL:

> "Although dictionary types can in general be nullable, they cannot when
used as the type of an operation argument or a dictionary member."
> https://webidl.spec.whatwg.org/#dfn-nullable-type

Note: this was missed before because the webidl2 checker did not validate
arguments in callback definitions. It now does.
