Rebinding a usertype doesn't work anymore

[gotschmarcel-ni]

It might be a strange use-case, but I noticed that rebinding a usertype doesn't work with 3.3.0, even though it did in 3.2.1. Is this a bug or an intentional change?

Here's a working 3.2.1: https://godbolt.org/z/4z1jr98PY Here's a broken trunk: https://godbolt.org/z/3sTc5ETM5 (this uses trunk, but I tested that this behavior also occurs with 3.3.0)
