.Deleting a `firewalld` rich rule with `forward-ports` works now as expected
Previously, the `firewalld` service incorrectly handled the deletion of rules with the `forward-ports` setting. As a consequence, deleting a rich rule with `forward-ports` from the runtime configuration failed. This update fixes the problem. As a result, deleting a rich rule with `forward-ports` works as expected.

Adam, can you show the firewalld logs from /var/log/firewalld? It appears that nothing is logged.

You can increase the log verbosity by add "--debug" in /etc/sysconfig/firewalld. So, as of this morning I'm unable to reproduce the issue. I'm not sure what changed, but everything is working. Strage, I am hitting this bug. It doesn't happen if I add --permanent before it, so I guess the solution for now is to remove the permanent rule and restart the firewall.

Can you confirm that you're using a rich rule with forward ports? Yes that is correct. Upstream:
4116829da430 ("test: add coverage for gh #482")
362ebff80161 ("fix: rich rule forward-port deletion after reload")
