### Steps to reproduce

1. Run provided example code
2. On the intitial screen press '+' fab button

What the app does is that it pushes PageTwo on a fab press and then after 100 ms that page performs pop() operation
After the aforementioned push() returns from await another page (PageThree) is pushed.

It sometimes (very rarely) works properly.
More often than not it crashes.

### Expected results

Route '/three' is visible with '/' page below it

### Actual results

Complete crash of navigation framework with error screen in debug mode and empty screen in profile mode

### Code sample

Code sample

```dart
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';

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

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

static final goRouter = GoRouter(

GoRoute(
path: '/',
builder: (context, state) {

},
),
GoRoute(
path: '/two',
builder: (context, state) {
return const PageTwo();
},
),
GoRoute(
path: '/three',
builder: (context, state) {
return const PageThree();
},
),
],
);

@override
Widget build(BuildContext context) {
return MaterialApp.router(
routerConfig: goRouter,
title: 'Bug Demo',
);
}
}

class MyHomePage extends StatefulWidget {
const MyHomePage({
super.key,

final String title;

@override
State createState() => _MyHomePageState();
}

class _MyHomePageState extends State {
int _counter = 0;

void _incrementCounter() {

}

@override

}

Future _goToPage2Then3(BuildContext context) async {
final goRouter = GoRouter.of(context);
await goRouter.push('/two');
goRouter.push('/three');
}
}

class PageTwo extends StatefulWidget {
const PageTwo({
super.key,
});

@override
State createState() => _PageTwoState();
}

class _PageTwoState extends State {
@override
void didChangeDependencies() {
super.didChangeDependencies();
final goRouter = GoRouter.of(context);
Future.delayed(
const Duration(milliseconds: 100),
goRouter.pop,
);

// Regular pop gives the same error
// final navigator = Navigator.of(context);
// Future.delayed(
// const Duration(milliseconds: 100),
// navigator.pop,
// );
}

@override
Widget build(BuildContext context) {
return const Scaffold(
body: Center(
child: Text('Page 2'),
),
);
}
}

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

@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
onPressed: () => Navigator.pop(context),
child: const Text('Page 3'),
),
),
);
}
}
