I guess it's because it's because firewalld.service has
"Conflicts=iptables.service", and thus (re)starting firewalld.service
stops iptables.service; fail2ban.service has PartOf to both, thus both
the restart and stop are propagated, and conflict.

Claiming a PartOf relationship to both of two conflicting services is
the problem here. I doubt such a use case was what PartOf was designed
to support.
