Incorrect rendering of display math environments in block quotes.

[pazner]

Describe the current behavior

The following example of a LaTeX display environment in a block quote does not render properly:

> This is a block quote
> $$
>     y = m x + b
> $$
> with an equation.

Describe the expected behavior

It should render like this (this is how it is rendered with jupyter nbconvert --to html, in GitHub, VSCode, etc.):
