Fails to parse because \left[ and \right] has to be on one line:

<math>
\begin{align}
&\left[123\\
&abc\right]
\end{align}
</math>

Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} &\left[123\\ &abc\right] \end{align} }

Works:

<math>
\begin{align}
&Line1\\
&Line2
\end{align}
</math>

${\begin{aligned}&Line1\\&Line2\end{aligned}}$ —User000name 07:02, 21 May 2016 (UTC)
