Description

Binding a key to Telescope's undo plugin causes custom keymaps to stop working.

Minimal, Reproducible Example

programs.nixvim = {
  plugins.which-key.enable = true; # helps see what's happening
  plugins.telescope = {
    enable = true;
    keymaps = {

        ###### the problematic line - comment this to "fix" the bug
        "<leader>fu" = { action = "undo";         options.desc = "Telescope Undo"; };

        # These should work fine
        "<leader>ff" = { action = "builtin";      options.desc = "Telescope Builtin"; };
        "<leader>fg" = { action = "live_grep";    options.desc = "Telescope Live Grep"; };
    };
    # NOTE: the undo plugin doesn't have to be enabled
    #extensions.undo.enable = true;
  };

  # test keymaps
  globals.mapleader = " ";
  keymaps = [
    {
      action = "<cmd>help<CR>";
      key = "gh";
      mode = [ "n" ];
    }
    {
      action = "<cmd>help<CR>";
      key = "yu";
      mode = [ "n" ];
    }
    {
      action = "<cmd>help<CR>";
      key = "<leader>g";
      mode = [ "n" ];
    }
  ];
}

Steps to reproduce

1. load nixvim with the config above
2. try using any of the custom keymaps (gh, yu, <leader>g)
   • they don't work (help page doesn't open)
   • note that <leader>ff and the other telescope.keymaps options work (as they should)
3. comment line 8 (the problematic line)
4. try using the custom keymaps from before
   • help page opens, they work
   • all other telescope.keymaps options still work
