I can start an other terminal (i.e. xterm) there are the groups correct. Starting a gnome-terminal from this terminal causes wrong groups in gnome-terminal. So either gnome-terminal sets the groups or uses a dbus/systemd/whatever funktion to set the groups. I would call both scenarios a bug in the gnome-terminal.
