A given diff node for a type can be hung off of several contexts: a
function parameter type node, another type diff node, etc. For that
reason, a type diff node should not have a parent node. Thus, it's
should be the job of the context containing the type diff node to
propagate its categories to the context nodes. This actually fixes a bug
about category propagation.
