firewalld does not normalize an address of ipset entries in CIDR notation.

Issue

• Add ipset via firewall-cmd --add-entry=10.0.1.0/22, but the 10.0.1.0/22 is not normalized in 10.0.0.0/22.
• It should be normalized in CIDR notation.

# firewall-cmd --permanent --info-ipset=test
test
  type: hash:net
  options:
  entries: 10.0.1.0/22   <<<--- 

• ipset command normalizes the address correctly.

# ipset l
Name: test
...
Number of entries: 1
Members:
10.0.0.0/22   <<<---

• Why the firewall-cmd doesn't normalize it? And how does the rule work; as 10.0.0.0/22 or 10.0.1.0/32?
