This is probably because you filter on bridge0.

There are some sysctl's related to this, run sysctl -a | grep bridge
I think in some combinations, pf sees packets on the bridge interface
with the wrong direction.

Do you have a particular reason for filtering on the bridge interface,
and not just on the physical interfaces?
