I can confirm that for this bug, I am not affected directly by suspend / resume actions. But the DNS still randomly fails during normal operation of the machine.
If I kill dnsmasq PID and restart it from the command line, then it works again.
sudo /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var/run/NetworkManager/dnsmasq.pid --listen-address=127.0.1.1 --cache-size=0 --conf-file=/dev/null --proxy-dnssec --enable-dbus=org.freedesktop.NetworkManager.dnsmasq --conf-dir=/etc/NetworkManager/dnsmasq.d &
