I have come to the conclusion that the issue is not with xfce4-power-manager. Even when xfce4-power-manager uninstalled and with the system only using systemd for suspend/resume, this issue occurs.
I do not know if this issue has affected anyone else. Since it is not xfce4-power-manager that is the problem, I will continue addressing this in Red Hat's bugzilla for systemd and/or logind
