Yes, this is a current limitation of the library. There was already a PR (#14357) to solve the issue but it was not accepted. The problematic part is restoring the helpers during the deserialization process since they depend on other objects. I guess my proposed solution at that time was not convincing since the necessary logic in ObjectLoader needs an additional step and introduces some redundancies 😇

Closing in favor of #16340.
