Description

The work that has been done for LU-1996 seems to have introduced an odd bug in changelogs when jobid_var=disable. I don't know enough about this area to speculate on severity, but it seems pretty serious to me. The upshot is that changelogs don't make sense with the default jobid_var setting.

Please see the attached reproducer script for details.
