and can talk to the hosts:
# ping6 ff02::2%br0

Can you try ff02::1 ?

same result.

Can you please try

# brctl showstp br0

To make sure STP state is set to forwarding?

it is.

Does it matter if you try IPv4 ping or if vlan_filtering is set 1?
Unfortunately, I can't reproduce on my switch.

Bring up the hosts and then reboot the switch. At that point I get no
host to host communication. As soon as I flap the port on host1 host3 to
host1 starts working.

So it seems to be something about the initial boot state.
