That can be addressed by adding a WantedBy= entry to the [Install] section corresponding to each Requires= entry in the [Unit] section.
That way when the target is reached it tries to start dnsmasq again.
One of the issues with the suggested fix (and the original
dnsmasq.service file) is that it still fails to ever start dnsmasq if
the Requires= target fails at boot, even if the target is eventually
reached.
