Preflight Checklist
What's Wrong?
RTL (Right-to-Left) text rendering is broken in the Claude Code chat panel since v2.1.63. When typing Persian/Farsi (or any RTL language) in the chat input or reading RTL text in responses, the characters appear reversed (displayed left-to-right instead of right-to-left). This issue does not occur in v2.1.61. The VSCode editor and terminal render RTL text correctly — the problem is only in the Claude Code webview panel.
What Should Happen?
RTL languages (Persian, Arabic, Hebrew, etc.) should render correctly in the Claude Code chat panel — both in user input and in assistant responses — with proper right-to-left direction, as they did in v2.1.61.
Error Messages/Logs
Steps to Reproduce
Install Claude Code extension v2.1.63 on VSCode (Windows 11)

Type any RTL text (e.g., Persian/Farsi: سلام دنیا) in the chat input
Observe that the characters are rendered in reverse order (left-to-right instead of right-to-left)
Downgrade to v2.1.61 → RTL text renders correctly again
