I couldn't replicate the issue on 22.05.

After setting the static IPv6 on the LAN interface and enabling DHCPv6 Server, I got the IPv6 address on my PC from the defined range.

Here is the generated ruleset:

# allow access to DHCPv6 server on LAN
# We need inet6 icmp for stateless autoconfig and dhcpv6
pass  quick on $LAN inet6 proto udp from fe80::/10 to fe80::/10 port = 546 ridentifier 1000002551 label "allow access to DHCPv6 server" 
pass  quick on $LAN inet6 proto udp from fe80::/10 to ff02::/16 port = 546 ridentifier 1000002552 label "allow access to DHCPv6 server" 
pass  quick on $LAN inet6 proto udp from fe80::/10 to ff02::/16 port = 547 ridentifier 1000002553 label "allow access to DHCPv6 server" 
pass  quick on $LAN inet6 proto udp from ff02::/16 to fe80::/10 port = 547 ridentifier 1000002554 label "allow access to DHCPv6 server" 
pass in  quick on $LAN inet6 proto udp from fe80::/10 to fc00::1 port = 546 ridentifier 1000002555 label "allow access to DHCPv6 server" 
pass out  quick on $LAN inet6 proto udp from fc00::1 port = 547 to fe80::/10 ridentifier 1000002556 label "allow access to DHCPv6 server"

I get the same ruleset generated after I copied the patched filter.inc file and reloaded the filter:

# allow access to DHCPv6 server on LAN
pass  quick on $LAN inet6 proto udp from fe80::/10 to fe80::/10 port = 546 ridentifier 1000002551 label "allow access to DHCPv6 server" 
pass  quick on $LAN inet6 proto udp from fe80::/10 to ff02::/16 port = 546 ridentifier 1000002552 label "allow access to DHCPv6 server" 
pass  quick on $LAN inet6 proto udp from fe80::/10 to ff02::/16 port = 547 ridentifier 1000002553 label "allow access to DHCPv6 server" 
pass  quick on $LAN inet6 proto udp from ff02::/16 to fe80::/10 port = 547 ridentifier 1000002554 label "allow access to DHCPv6 server" 
pass in  quick on $LAN inet6 proto udp from fe80::/10 to fc00::1 port = 546 ridentifier 1000002555 label "allow access to DHCPv6 server" 
pass out  quick on $LAN inet6 proto udp from fc00::1 port = 547 to fe80::/10 ridentifier 1000002556 label "allow access to DHCPv6 server"

The 22.05 system that had the same symptom ended up being user error. However 23.01 is still an issue.
