Markdown RTL text rendering broken after latest VS Code update (Arabic text)

[AhmedElTabarani]

Does this issue occur when all extensions are disabled?: Yes/No

After the latest VS Code update (1.106.0), the editor started rendering Arabic (RTL) text inside Markdown incorrectly

I have to file with the same content/text, one is .md and the other is .txt

The .txt file is mostly right, and it displays the text as it was before the update

The original word is السلام عليكم, but VS Code displays it incorrectly as سلام عليكم ا the first letter (ا) gets moved to the end of the word

It’s similar to writing elcomew instead of welcome, the first letter becomes the last letter

The second line is test: عنوان, it should display as it does in the github issue
As you noted, VSCode displays it as test: نوان ع and عنوان :test instead of test: عنوان

The rest of the lines displayed in the .txt file are mostly right as it was before the update

BTW, look below (last section of this issue) to see how GitHub renders the same content completely perfect without any issues

I figured it out, it was because the YAML extension from Red Hat https://github.com/redhat-developer/vscode-yaml

But, strangely, the issue appears after updating VS Code to 1.106.0
Anyway, I will close it now and repost the issue in their repo
