Latex issue with underscores

[jakobkogler]

The following example doesn't display correctly.

$$\underbrace{1}_{2} \underbrace{1}_{2}$$

A fix is to escape the underscores.

$$\underbrace{1}\_{2} \underbrace{1}\_{2}$$

Not sure why this happens.
Maybe the markdown converter recognizes _something_ as the italic font style, and this conflicts with the formula.

Yes, I'm afraid it is similar to #236 - markdown parsing interferes with latex syntax. I failed to find a robust way to mask latex at the first attempt. I'll try again bit later.
