Not a kernel issue - this is fixed in the latest fstests.

You are running a test in the "dangerous_fuzzers" group that isn't
in the auto group. This is a test for developers to find error
detection issues and, as such, failure is kinda expected. It is not
regression test that can be used for pass/fail testing....

Cheers,

Dave.
