Only first latex equation rendered in line

[benjaminirving]

Hi,

Firstly, thanks for the great tool. It seems that there is a small bug where only the first latex equation in each line is rendered.

e.g.
$$ x^2 $$ and $$ x^3 $$

results in just the x^2 being rendered. Unless there is a bug with my setup.

p.s. had a look in cm-extend-autopreview.js but my javascript abilities are non-existent

Also previewing latex equations on multiple lines doesn't render:

$$  
x^2  
x^3  
$$

Otherwise great tool, Thanks
