My initial investigation reveals that this started acting up in nova/stable/newton only after this following neutron patch was backported to neutron/stable/newton: https://review.openstack.org/#/c/470297/

If I manually restore these two changes in neutron/plugins/ml2/driver_context.py and restart neutron-server, I no longer see the problem:

        self._binding = copy.deepcopy(binding)
        self._binding_levels = copy.deepcopy(binding_levels)
