I also trying confront with this problem, but there is no solution at all. I tried to disable the systemd-resolved service but after that my domain resolver stop working and I lost access to webpages. I also have dnsmasq. I don't know why but I think this service is come from Ubuntu 16.04. I upgraded my Ubuntu from 16.04 to Ubuntu 17.10 and then upgrade it to 18.04. Maybe this is why the problem is created.
