[morph.ai] Fixed PLAYGROUND-PR-3457 -- Fix for bold + italics combined markdown rendering

[MorphCodeBot]

Issue

Markdown text with combined bold and italic formatting (using *** or ___) would cause incorrect rendering, making the rest of the document appear in bold and italics.

Changes

• Added new variants to the BOLD definition in markdown.js
• Created specific patterns for triple asterisks (***) and triple underscores (___)
• Applied combined 'strong emphasis' className for proper styling
• Prioritized these patterns by placing them at the start of the variants array

Testing

Before/after screenshots in the ticket show the proper rendering of combined bold and italic formatting.

Impact

This fix ensures proper rendering of markdown text that uses combined bold and italic formatting without affecting the rest of the document.
