Description

In the past, we had many bugs from type serializers that have not properly implemented the duplicate() method in a proper way. A very common error is to forget about creating a deep copy of some fields that can lead to concurrency problems in the backend.

We should add a test case for that tests duplicated serializer from different threads to expose concurrency problems.
