Very often Bash 5.2 would suddenly stop saving command history which has been confusing me for quite some time. Today I did some debugging and came up with the following minimal scenario to reproduce the problem.
$ bash --version GNU bash, version 5.2.0(18)-beta (x86_64-apple-darwin21.5.0) Copyright (C) 2022 Free Software Foundation, Inc.
