rhel8/9: log limit of firewalld with rich rules not working properly

Issue

• We would like to limit logs of firewalld. Therefore, we created a rich rule for firewalld to limit logs to twice a day as the following command on RHEL8.

# firewall-cmd --permanent --zone=XXX \
  --add-rich-rule='rule family="ipv4" source address=198.51.100.131/24 service name=all log prefix="IN_BOUND_XXX " level="info" limit value="2/d" accept'

• However, more than 2 log entries are generated per day.
• We can reproduce it on RHEL8.1 to RHEL8.7. On the other hand, we can limit logs by the same command on RHEL7.
