issue with match_mark regex

[robertc99]

I getting a warning out of the firewall module 8.0.0) on a rule created by podman
The warning is

Warning: Provider returned data that does not match the Type Schema for firewall[9031 netavark portfw masq mark]
Value type mismatch:
* match_mark: 0x2000/0x2000 (expects an undef value or a match for Pattern[/^(?:!\s)?[a-fA-F0-9x]+$/], got '0x2000/0x2000')

I believe rules causing the problem are
-A NETAVARK-HOSTPORT-MASQ -m comment --comment "netavark portfw masq mark" -m mark --mark 0x2000/0x2000 -j MASQUERADE
-A NETAVARK-HOSTPORT-SETMARK -j MARK --set-xmark 0x2000/0x2000
