Arabic Text Rendering Issue with Specific Letter in Flutter

### Steps to reproduce

## Environment

**Flutter version**: Flutter 3.19.1 • channel stable
**Simulator**: XCode
**Target Platform and Version**: iOS 17
**Devices Tested**: iPhone 15

--------

Hello everyone!

I've encountered a rendering issue in my Flutter application where a specific Arabic letter/ligature (الإ) does not display correctly. This problem occurs with certain fonts, such as Google's Lateef and Scheherazade New. Interestingly, the issue is not present when using the Amiri font, where the text renders as expected. A while ago, everything was working fine with Lateef, and I'm unsure what changes might have caused this issue to arise now.

### Expected results

The expected behavior is for the Arabic letter/ligature to render correctly in the application, similar to how it renders when using the Amiri font or when viewed in web browsers and other platforms outside of Flutter.

This is Scheherazade New on Google's website;

### Actual results

When using the Lateef and Scheherazade New fonts, the specific Arabic letter/ligature appears incorrectly (parts of the letter are not disconnected when they should be. This is despite these fonts supporting the letter correctly in other environments and platforms.

### Code sample

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Arabic Text Rendering Issue Demo'),
),
body: FontTestWidget(),
),
);
}
}

class FontTestWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
// Define the style for each font for consistency
TextStyle textStyle(double size) => TextStyle(fontSize: size);

return SingleChildScrollView(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('Using Lateef Font:', style: textStyle(24)),
Text(
'الآ',
style: textStyle(24).copyWith(fontFamily: 'Lateef'),
),
Divider(),
Text('Using Scheherazade New Font:', style: textStyle(24)),
Text(
'الآ',
style: textStyle(24).copyWith(fontFamily: 'Scheherazade New'),
),
Divider(),
Text('Using Amiri Font (for comparison):', style: textStyle(24)),
Text(
'الآ',
style: textStyle(24).copyWith(fontFamily: 'Amiri'),
),
],
),
);
}
}
```
