That makes sense, however I don't know whether it's a good idea or not,
https://bugzilla.mozilla.org/show_bug.cgi?id=1011237 and I suspect
MathJax and other LaTeX-to-MathML converters assume that mtable does not
set displaystyle to "false". Alignment features are only implemented in
MathPlayer and so most people use mtable to implement things like

\begin{align*}
\int_a^b f(x) &= ... \\
&= ...
\end{align*}

where we expect the content to inherit displaystyle. In any case, it
seems that the spec should be clarified.
