I can confirm this worked in 6.0-R and is broken in 6.1-R, and I can
confirm it was the commit by ume at freebsd.org mentioned in the past log
entries of this PR that broke it:

In my case, I don't see the backup constantly switching, instead I see
both the master and backup constantly acting as master, but only on the
IPv6 interface - the IPv4 interface works as expected. This difference
could be due to te fact that I have the IPv4 interface on this machine
also under carp's control, although I do have sysctl
net.inet.carp.preempt=1, which in theory should mean that all interfaces
track each other's state.
