The missing step here is
DROP OWNED BY test_role;
You have to use that to get rid of "initial privileges" because
neither REVOKE nor ALTER DEFAULT PRIVILEGES will touch existing
initial privileges. Pre-v17 didn't account for this properly
and would allow you to drop the role anyway, leaving dangling
entries behind in pg_init_privs. While those are harmless in
isolation, they cause problems for later dump/restore activity.
