bug: Kitty's .desktop file opens in gedit on Linux Mint w/Cinnamon

Issue description

When writing the following HM nix code (running on a Linux Mint w/Cinnamon) kitty shows up in the start-menu (as expected). However, when clicking on the kitty start-menu item (whose icon is not found btw), the Cinnamon code editor (gedit?) opens up with the bash script generated by nixpkgs's wrapProgram, instead of opening Kitty.

{config, lib, ...}: {
  targets.genericLinux.enable = true;
  programs.kitty.enable = true;
  xdg.desktopEntries.kitty = let
    kitty = config.programs.kitty.package;
  in {
    name = "Kitty";
    type = "Application";
    genericName = "Terminal Emulator";
    comment = "Fast, feature-rich, GPU based terminal";
    icon = "kitty";
    exec = lib.getExe kitty;
    categories = ["X-Desktop" "X-System"];
    settings = {
      TryExec = lib.getExe kitty;
      X-Version = lib.getVersion kitty;
    };
  };
}

Just confirmed it, if I

1. copy the resulting kitty.desktop file out of /nix/store
2. chmod +x it
3. place the copy (or a symlink pointing to the chmodded copy)

it works. If I remove the executable bit chmod -x, it stops working.

Can this be fixed somehow?
