Nested GetRouterOutlet not working

[LuisGMM]

Describe the bug Using doubly nested GetRouterOutlet causes the second router to.. disappear? I really have no idea what is happening. Repo: https://github.com/LuisGMM/get_bug_example

Reproduction code

app_routes.dart

// Remove analyzer from this file
// ignore_for_file: constant_identifier_names

import 'package:project/app_pages.dart';

/// Used to define all the routes in the application.
/// Use it along the `Get.*Named()` methods to navigate to the desired screen.
abstract class AppRoutes {
  AppRoutes._();

  static const String INIT = HOME;

  static const String HOME = AppPaths.HOME;

  static const String INVENTORY = AppRoutes.HOME + AppPaths.INVENTORY;

  static const SETTINGS = HOME + AppPaths.SETTINGS;
  static const SETTINGS_PROFILE = SETTINGS + AppPaths.SETTINGS_PROFILE;
  static const SETTINGS_SUPPORT_NOTIFICATION = SETTINGS + AppPaths.SETTINGS_SUPPORT_NOTIFICATION;
}

/// Used to define all the paths in the application.
/// They are not used directly for navigation, but are used to
/// build the routes in the [AppRoutes] class and the pages
/// in the [AppPages] class.
abstract class AppPaths {
  AppPaths._();

  static const HOME = '/home';

  static const INVENTORY = '/inventory';
  static const SETTINGS = '/settings';
  static const SETTINGS_PROFILE = '/profile';
  static const SETTINGS_SUPPORT_NOTIFICATION = '/support-notification';
}

  }
}

main.dart

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:project/app_pages.dart';
import 'package:project/nav_bar_screen.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(title: 'Flutter Demo', home: NavBarScreen(), getPages: AppPages.pages);
  }
}

To Reproduce Steps to reproduce the behavior:

1. Add the code into a GetMaterialApp
2. Click on the 'Settings' button
3. Click on 'Wtf is going on?'
4. The 'Wtf is going on?' disappears

Expected behavior As with the column of buttons, I expected the bottomNavigationBar to remain in place, instead it disappears and opens the AppRoutes.SETTINGS_SUPPORT_NOTIFICATION in "Full screen" next to the column of buttons.

Screenshots Go to settings

Here we can see the bottom bar (I tried adding columns & rows to the body too, same result):

However, after clicking on it we see the new page, but the bottom bar wen on holidays :(

Describe on which device you found the bug: ex: settings_screen.dart.

Minimal reproduce code I made a repo with it: https://github.com/LuisGMM/get_bug_example

Note this example also suffers this bug: https://github.com/jonataslaw/getx/issues/3336

Oh and I based this example on the @jonataslaw example:

Another thing, sorry, I tested it on the web, like this: flutter run -d chrome
