The Dock icon for Firefox-esr has been replaced with a settings icon.

Description

The Dock icon for Firefox-esr has been replaced with a settings icon, but it displays normally in the launcher interface or other interfaces.
When using the rofi or noctalia launcher to open, the icons in the dock are also normal.

Steps to Reproduce

Configure niri shortcuts for firefox-ser, use the shortcut to open firefox-ser.

Nix Config：

wayland.systemd.target = "niri.service";
  programs.noctalia-shell = {
    enable = true;
    systemd.enable = true;
    settings = lib.importJSON ./settings.json;
  };

  home.sessionVariables = {
    QS_ICON_THEME="Papirus";
    QT_QPA_PLATFORM = "wayland;xcb";
    QT_QPA_PLATFORMTHEME = "qt6ct";
    QT_AUTO_SCREEN_SCALE_FACTOR = "1";
  };


  home.packages = with pkgs; [
    papirus-icon-theme # Papirus 图标
    qt6Packages.qt6ct  # Qt6 的配置工具
  ];

  gtk= {
    enable = true;
    iconTheme = {
      name = "Papirus";
      package = pkgs.papirus-icon-theme;
    };
  };

  gtk.gtk2.enable = true;
  gtk.gtk3.enable = true;
  gtk.gtk4.enable = true;
