Sorting of case class properties no longer works as of 2.20

Can be reproduced with the following test case:

This test cases passes with 2.19.2 and fails with 2.20.0. I thought it might be related to https://github.com/FasterXML/jackson-databind/issues/3900, but disabling `MapperFeature.SORT_CREATOR_PROPERTIES_FIRST` does not resolve the issue.
