[BUG] RTL (Right-to-Left) text rendering broken in latest version

What's Wrong?

Hebrew (and presumably other RTL languages) text was previously readable in the VS Code chat panel, even without full RTL support. After updating to the latest version, the text rendering broke completely — Hebrew text is unreadable/garbled in the chat panel.

Expected behavior:
Hebrew text should be readable as it was in previous versions (even without full RTL layout support)

Actual behavior:
Hebrew characters are displayed incorrectly / text is unreadable

Workaround:
Downgrading to the previous version restores the correct behavior

Environment:

• Claude Code version (broken): 2.1.63
• Claude Code version (working): 2.1.61
• OS: Windows

What Should Happen?

Hebrew text should render correctly in the VS Code chat panel, as it did in previous versions. While full RTL layout support (right-to-left text alignment) is not required, Hebrew characters must at minimum be displayed in a readable and logical order without distortion or garbling.
