Issue description

I wanna create symlink of gtk-4.0 stuff for libadwaita apps. However, I can't and it seems bug. I confirm that gtk.css exits in package and /nix/store/*-home-manager-files/.config/gtk-4.0/

# home.nix
xdg.configFile = {
  "gtk-4.0/assets".source = "${config.gtk.theme.package}/share/themes/${config.gtk.theme.name}/gtk-4.0/assets";
  "gtk-4.0/gtk.css".source = "${config.gtk.theme.package}/share/themes/${config.gtk.theme.name}/gtk-4.0/gtk.css";
  "gtk-4.0/gtk-dark.css".source = "${config.gtk.theme.package}/share/themes/${config.gtk.theme.name}/gtk-4.0/gtk-dark.css";
    };

$ lla ~/.config/gtk-4.0
