Math example from GitHub docs broken

This is an excerpt from the GitHub docs Writing mathematical expressions:

However, inserting verbatim:

**The Cauchy-Schwarz Inequality**

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

does not render:

@mlondschien I just tried this but with the empty line separator removed. It looks like it's rendering now?

Without empty line

Thanks, @Dusch4593. Is this intended?

@mlondschien I'm not sure, really. I actually just tried this on a small repo and both examples I gave actually rendered correctly:

But when I tried the same markdown in a thread comment (like you did initially in this issue), I got this:

I'm starting to wonder if this issue is originating from MathJax since this is ultimately a rendering issue?
