Consider this markup:
* MATHEMATICS AUXILIARY
** deriving sines and cosines
#+caption: Right triangle with two $\pi\big/4$ angles.
If I remove the second $\big/$, the first latex, $\pi\big/4$, in the caption will not properly render on export to html. Include it and both render just fine. Without the second, the first looks like this:
Figure 1: Right triangle with two \(\pi\big/4\) angles.
Is this a bug?
