The following card shows with the LaTeX always revealed:

**** Mathematical definitions                                      :drill:

The variance of a probability distribution is defined mathematically as:

[ $$\text{var}_x = \int dx p(x) (x - E[x])^2$$ ].


If I remove the [ and ] inside the cloze, it works as expected. Is there anyway around this, or should I use different LaTeX characters?
