I messed up masking my username. pc@user should be something like user@ubuntu or whatever.

Hi, just a short question. Does anybody knows why this

$$ \sqrt{\frac{\sum_{i=1}^{n}\left(\hat{r}_{ui}-r_{ui}\right)^2}{n}} $$

does compile to pdf (using the latex writer) but it doesn't compile to html? I think the problem is with

$\hat{r}$

But I'm totally lost with any probable cause. The dollar signs are being escaped somehow.

My pandoc version is

pc@user$ pandoc --version

pandoc 1.19.2.1

Compiled with pandoc-types 1.17.0.4, texmath 0.9, skylighting 0.1.1.4
