Fixed by #72311

@jkotas the failure persist even in that PR and subsequent PRs. Actually that PR enables other failures too, see #72330

It kind of fixed what it was meant to fix but the test uses a flawed detection logic that doesn't work with trimming. We also started running tests that are not meant to run with file locking disabled because of the flawed detection.

#72331 should fix it.
