Dollarmath math blocks inside blockquotes retains ">" in the equation.

[livinNector]

Describe the bug

context

When rendering dollar math blocks inside block quotes, such as the example below.

> Given
>
> $$
> x^2 + y^2 = 9
> $$
>
> What is the radius of the circle?

bug

The ">" symbol is retained in the rendered equation as shown below.

<blockquote>
<p>Given</p>
<div class="math block">
&gt; x^2 + y^2 = 9
&gt;
</div>
<p>What is the radius of the circle?</p>
</blockquote>

expectation

The math block should not contain ">" (>) inside the equation.

<blockquote>
<p>Given</p>
<div class="math block">
x^2 + y^2 = 9
</div>
<p>What is the radius of the circle?</p>
</blockquote>
