Cannot use ```math code block

**Describe the bug**
There is no option to use the `math` fenced code block in the style of GitHub to render LaTeX expressions. (But I might have missed the option.)

**To Reproduce**

Write
~~~markdown
This is the Pythagorean equation
$$
a^2 + b^2 = c^2
$$
This is the Pythagorean equation
``` math
a^2 + b^2 = c^2
```
~~~
The top one renders via a LaTeX renderer, the bottom one does not.

**Expected behavior**
I would like a code block rendered with ` ```math ``` ` to be displayed with a LaTeX renderer as if it has been written surrounded by $$ $$.
