Menu app name 'Maps' is currently 'org.gnome.Maps' after GTK overlay removal
See current image below:
This seems to have come from a deletion in commit:
57042c86fd468de2ed2808ca8bc3f7cbc114b171
of line:
GLib.set_application_name(_("Maps"));
in:
src/application.js
Reinstating the line corrects the menu. See image below.
