This is cute but it seems that expressions spanning multiple lines are not rendered

OK:

$$\|\vec{x} - \vec{p}_c\| = v(t_c-t_0)$$

--

NOT OK:

$$

\|\vec{x} - \vec{p}_c\|

= v(t_c-t_0)

$$

This makes larger latex expressions pretty impractical e.g. https://github.com/jurasofish/multilateration/blob/master/re...
