Github Latex not rendering properly

[lokehagberg]

Example: $works$

$f + a + i = l + s$

$$w_o_r_k_s$$

This is a variable $fails$, why does it not render $p$?

Neither does this o $n$ e!

At least it does not render in the Preview.

Can you show the code you are using to generate this letters?

The preview I had when I created the thread has changed, so things that did not work then does work now.
