Method Set.prototype.forEach called on incompatible receiver #<Set> thrown when applying patches.

🐛 Bug Report

I have a map that I am storing a set of ids in, with the key of the map being dynamic. If the set is already in the map when the id is added everything works as expected but if I try to create the set and add it to the map it fails when trying to use the produced patches. There is no issue with the produced value.
