markdown inline HTML problem

[robbwu]

The following LaTeX code enclosed in markdown:

{% markdown %}
<p>
$$
\mathbf{V}_1 \times \mathbf{V}_2 =  \begin{vmatrix} \mathbf{i}&\mathbf{j}&\mathbf{k} \\ 
\frac{\partial X}{\partial u}&\frac{\partial Y}{\partial u}&0 \\ 
\frac{\partial X}{\partial v}&\frac{\partial Y}{\partial v}&0 \end{vmatrix} 
$$
</p>
{% endmarkdown %}

Hyde would translate the & and \ into something else; which is not compatible with
markdown documentation:

Note that Markdown formatting syntax is not processed
within block-level HTML tags. E.g., you can’t use
Markdown-style emphasis inside an HTML block.

I also tried standalone version of python-markdown; it conforms to the documentation above.
This behavior is very useful for me to write LaTeX code for MathJax to render it.

Could you please tell me how to resolve this problem?

Thank you,
Robb

I found the reason;
The typogrify filter does the transformation.
