Roaming between IPv4 and IPv6?

Is wireguard supposed to be able to handle roaming between IPv4 and
IPv6? If I setup a tunnel to a dual-stack machine and establish the
tunnel using IPv6, then switch to a different interface (from WiFi to
cellular in this case) that doesn't have IPv6, the tunnel stops having
connectivity. Whereas if I go in the other direction (first establish
the tunnel over IPv4), I can seamlessly roam between different

Is this expected behaviour, or should v4/v6 roaming work?
