Description
Simple LaTeX equations are rendering correctly in markdown preview, but complex multiline mathematical expressions are failing to render.

$$\frac{\partial f}{\partial x} = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$$$$\sum_{i=1}^{n} i^2 = \frac{n(n+1)(2n+1)}{6}$$These render correctly.
Currently Broken
The following advanced multiline equations do NOT render:
$$
\mathcal{J}_{\text{CISPO}}(\theta) = E_{(q,a) \sim \mathcal{D},\, \{o_i\}_{i=1}^G \sim \pi_{\theta_{\text{old}}}(\cdot \mid q)}
\left[
\frac{1}{\sum_{i=1}^G |o_i|} \sum_{i=1}^G \sum_{t=1}^{|o_i|}
\text{sg}(\hat{r}_{i,t}(\theta))\, \hat{A}_{i,t} \log \pi_\theta(o_{i,t} \mid q, o_{i,\lt t})
\right],
$$$$
\hat{r}_{i,t}(\theta) = \text{clip}\!\left(r_{i,t}(\theta),\; 0,\; 1 + \epsilon^{IS}_{high}\right).
$$$$
\hat{A}_{i,t} = \sum_{p=t}^{T} \left(r_p^{\text{speed}} + r_p^{\text{perf}}\right) - B_i
$$
Possible Causes
Unsupported LaTeX Features
Current renderer may not support:
- multiline block parsing
- advanced macros
\mathcal\text{}- nested subscripts/superscripts
- escaped spacing commands
- large operators
- multiline environments
Likely Technical Issues
1. Missing Proper Math Engine
Current markdown parser may only support basic KaTeX/MathJax parsing.
2. Block Parsing Failure
Renderer may fail when:
$$ spans multiple lines- equation contains indentation/newlines
3. Unsupported Commands
Potential unsupported commands:
\text{}
\mathcal{}
\left[
\right]
\epsilon
\sim
Required Fix
Recommended Solution
Use full-featured math rendering support with:
with proper block equation configuration.
Required Capabilities
The renderer must support:
- multiline
$$ ... $$
- nested expressions
- large equations
- advanced symbols
- scientific notation
- AI/ML mathematical papers formatting
Important Rendering Requirement
Preserve Multiline Formatting
Do NOT collapse multiline equations into one line.
Expected Result
All provided equations should render correctly in preview exactly like:
- GitHub markdown math
- Obsidian
- Jupyter Notebook
- modern LaTeX-supported markdown editors
Additional Recommendation
Add Error Fallback
If equation parsing fails:
- show readable error message
- highlight invalid LaTeX section
- avoid breaking entire preview rendering
Priority
High — complex scientific/technical markdown rendering currently broken.
