[Bug]: Request permission returns `permanentlyDenied` when iOS app minimized while permission dialog is open

### Please check the following before submitting a new issue.

- [X] I have searched the [existing issues](https://github.com/baseflow/flutter-permission-handler/issues).
- [X] I have carefully [read the documentation](https://github.com/Baseflow/flutter-permission-handler/blob/main/permission_handler/README.md) and verified I have added the required platform specific configuration.

### Please select affected platform(s)

- [ ] Android
- [X] iOS
- [ ] Windows

### Steps to reproduce

1. Request for notifications permission on iOS (when current status is `.denied` meaning that it was not asked yet)
2. Minimize the application by clicking home button/sliding up

### Expected results

The dialog should either remain open or the `PermissionStatus` should stay as `.denied`.

### Actual results

Dialog closes and `Permission.notification.request()` returns `PermissionStatus.permanentlyDenied`.
After refreshing the app the status is `PermissionStatus.denied` again

### Code sample

Code sample

```dart
class MainApp extends StatelessWidget {
const MainApp({super.key});

@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: TextButton(
onPressed: () async {
final result = await Permission.notification.request();
print(result);
},
child: const Text('Request Permission'),
),
),
),
);
}
}
```
