Multi-Line Equation Rendering with Unnecessary Markdown Marks

[Navxihziq]

Issue Description

When converting multi-line equations, the output would includes unnecessary leading "latex" and trailing "" markdown marks. These marks appear in the rendered equations on the demo website, disrupting the intended display and readability of content.

Expected vs. Actual Behavior

• Expected: Equations rendered without any markdown formatting marks, maintaining clarity and presentation quality.
• Actual: Output contains "latex" and "" marks, affecting equation readability and presentation.

Steps to Reproduce

1. Navigate to the demo website.
2. Upload the provided picture
3. Observe the rendered output

Suggested Fix
Implement a regex-based solution to strip the leading and trailing markdown marks from equations before rendering.
Possible pattern: /^```latex\s+|\s+```$/g
