Overview

Fix Mermaid diagrams disappearing when attributes/classes change by re-rendering only on actual theme changes.

Closes #1884

Files changed

• patches/@theguild__remark-mermaid.patch
• pnpm-lock.yaml

What changed

• Patch @theguild/remark-mermaid Mermaid renderer:
  • Track current theme state (isDark)
  • Re-render Mermaid only when the theme state changes

How to reproduce

1. Open a page with Mermaid diagrams (e.g. Introduction)
2. Click the language/version dropdown OR toggle the mobile hamburger menu
3. Before: diagrams disappear
4. After: diagrams stay visible

Testing

• Verified locally on desktop and mobile viewport
• Confirmed Mermaid diagrams remain stable across dropdown/menu toggles
• Confirmed diagrams still update correctly when switching dark/light theme
