Should set window title
The window title (shown in the gnome-shell overview) is currently showing as "org.gnome.Maps". Looking in the Inspector it seems the title property is NULL, so we should probably set it explicitly to "Maps" as it seems to fall-back on the app-id (not sure why it doesn't pick the name from the .desktop file). This should be safe to add before 3.32 (just before the 3.31.92 release), since this will not be a new translatable string (the app name already appears in other places).
