using interface groups in pf tables stopped working in 13.0-RELEASE

I dont think so. Everything works normally if I switch from group name to interface name
in the config. 

It seems to me that pf for some reason changed how it interprets group names differently from
12.2-RELEASE-p4 and 13.0-RELEASE. 

I dont really get how "anchor in from trusted:network” can resolve to "anchor in inet6 all”
