Thumb button behaving differently on MX Master 4 after upgrading to Fedora Workstation 44

[Programazing]

After upgrading to Fedora Workstation 44, the thumb rest click has started to act like "KEY_BACK" instead of "KEY_LEFTMETA." Everything else works fine.

  // ── Thumb rest click ────────────────── Super/Windows key
  {
    cid: 0x1a0;
    action: {
      type: "Keypress";
      keys: [ "KEY_LEFTMETA" ];
    };
  },
