Arabic Text Display Issue: Reversed Letters and Unconnected Characters in VS Code Extension After Versions Beyond 2.1.59

Description:
After updating to versions beyond 2.1.59 of the extension in Visual Studio Code, Arabic text appears with reversed letters and unconnected characters. This issue was not present in 2.1.59 and everything worked fine in that version.

Details:

• Affected Version: All versions after 2.1.59
• Non-Affected Version: 2.1.59 (works correctly)
• Environment: Visual Studio Code (VS Code Extension)
• Description: Arabic text appears with reversed letters and unconnected characters.
• Reproducibility: The issue happens every time after updating to versions beyond 2.1.59.

Steps to Reproduce:

1. Update to version 2.1.6x or any newer version of the extension.
2. Open any file or editor in Visual Studio Code.
3. Start typing Arabic text.
4. Notice that the letters appear reversed and unconnected.

Expected Behavior:
Arabic letters should be properly connected and displayed correctly, just like in 2.1.59.

Note:

• This issue did not occur in 2.1.59 or any earlier versions.
• The issue began after the update to versions beyond 2.1.59.
