Fix web chat streaming markdown gibberish#505
Merged
Conversation
The marked.js parser was producing garbled output when receiving incomplete markdown during streaming (e.g., unbalanced ** for bold text). Added a hasBalancedMarkdown() check that validates markdown markers are balanced before rendering, falling back to plain text if not. - Uses arithmetic instead of lookbehind regex for Safari < 16.4 compatibility - Checks for balanced **, *, `, and ``` markers - Falls back to plain text rendering when markers are unbalanced - Final message is always rendered with full markdown after streaming completes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
