Commit c1ec7b2ff meant to fall back to the base layout in case a variant like `fr+oss` is set up, but as we are checking for '+' on the array rather than the layout name, the fallback only "works" for a layout that is literally called '+', whoops. https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2471 (cherry picked from commit d29e5765badbca21a6ef8b40087a8e3587b15dd4)
