I'm experiencing incorrect and seemingly inconsistent behavior when nesting
`\begin` `\end` environments inside `\(\)` or `$$`. For example, the
following is valid latex code:
```
\(\begin{aligned}
b_n &= \frac{1}{\pi} \int_{0}^{\pi} x \sin{\left(nx\right)}dx \\
b_0 &= 0 \\
\int_{0}^{\pi} udv &= \left[uv\right]_{0}^{\pi}
  - \int_{0}^{\pi} vdu \\
dv &= \sin{\left(nx\right)}dx \\
v(x) &= \int \sin{\left(nx\right)}dx \\
&= -\frac{\cos{\left(nx\right)}}{n} \\
\left[uv\right]_{0}^{\pi} &=
  -\left[\frac{x\cos{\left(nx\right)}}{n}\right]_{0}^{\pi} \\
&= \left\{\begin{alignedat}{2}
  \frac{\pi}{n}&, && \quad \text{$n$ odd} \\
  -\frac{\pi}{n}&, && \quad \text{$n$ positive even} \\
\end{alignedat}\right. \\
\int_{0}^{\pi} vdu &=
  \int_{0}^{\pi} -\frac{\cos{\left(nx\right)}}{n} dx \\
&= -\frac{1}{n^2} \left.\sin{\left(nx\right)}\right|_{0}^{\pi} \\
&= 0 \\
b_{n\in \mathbb{Z}^+} &= \left\{\begin{alignedat}{2}
  \frac{1}{n}&, && \quad \text{$n$ odd} \\
  -\frac{1}{n}&, && \quad \text{$n$ positive even} \\
\end{alignedat}\right. \\
\end{aligned}\)
```
But this confuses org which is generating images for the `\begin{aligned}`
at the top and the `\text` macros, but nothing else. Iterations on this
sometimes work fine, however. For example,
```
\(\begin{aligned}
b_{n\in \mathbb{Z}^+} &= \left\{\begin{alignedat}{2}
  \frac{1}{n}&, && \quad \text{$n$ odd} \\
  -\frac{1}{n}&, && \quad \text{$n$ positive even} \\
\end{alignedat}\right. \\
\end{aligned}\)
```
typesets correctly. Has anyone else had trouble with the latex fragment
regex's?
