bug: swaync causes xdg-desktop-portal to run into a timeout

[Ma27]

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• I have searched the existing issues

Issue description

When xdg-desktop-portal is enabled on NixOS via

{
  xdg.portal = {
    enable = true;
    extraPortals = with pkgs; [ xdg-desktop-portal-gtk xdg-desktop-portal-wlr ];
    config.common.default = "*";
  };
}

and services.swaync.enable = true; is set to true in home-manager, the desktop portal runs into a timeout. I use the sway module from home-manager with the sway-session.target systemd-target.

I should add that I'm using impermanence and on the very first start of my desktop session I activate my home-manager config like this:

{
  programs = lib.genAttrs [ "zsh" "bash" ] (shell: {
    interactiveShellInit = ''
      if ! [[ -v TRIED_HOME_MANAGER_ACTIVATE || -e $HOME/.config/environment.d/10-home-manager.conf ]]; then
        hm="$HOME/.local/state/nix/profiles/home-manager"
        [[ -x $hm/bin/home-manager-generation ]] && $hm/bin/home-manager-generation
        export TRIED_HOME_MANAGER_ACTIVATE=1
        exec ${shell} -l
      fi
    '';
  });
}

The following change to my home configuration has solved the problem:

I'm not entirely sure why which is why I didn't file a PR yet.
Does it make sense to make the target configurable here via systemdTarget as it's the case in other modules?
