Hi just FYI: I solved it.
The trick was that within the second g_application_run(), the app menu must be attached to the application using gtk_application_set_app_menu() *before* adding the already existing _window_ using gtk_application_add_window() to the application. This way the app-menu is properly (or still) shown in the same window throughout both GtkApplication instances.
