Type canonicalization is deferred between in may involve cycles. Instances are canonicalized eagerly, but their type arguments are not necessarily canonical yet, which can lead to incorrect canonicalization of the instance. The work around is to include the most popular type arguments in the serializer's set of base objects, bypassing deferred canonicalization. Other type arguments will continue to fail.
