Which seems to be a result of the session scope of Debian-gdm not being
stopped when the gdm service is stopped, so if you run systemctl stop
gdm.service, the session scope is still running, along with all its
processes:

As a workaround, I added
ExecStopPost=/bin/loginctl kill-user Debian-gdm
to gdm.service. This seems enough to make
systemctl restart gdm.service
work
