Subject: Inline math in "\(\)" pairs won't highlight in captions
Date: Mon, 29 May 2017 17:28:22 -0700

[Message part 1 (text/plain, inline)]

The following minimal example

\documentclass{article}

\begin{document}
\begin{figure}
  \centering
  \caption{Math \(x=y\) and $x=y$.}
\end{figure}
\end{document}

$x=y$ is highlighted but \(x=y\) is not. Perhaps both should be highlighted?

Yes, I agree this is an inconsistent behavior, but you already
reported the issue one month ago:

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I vaguely remember that the LaTeX team once said that there is no
special need to use \(.\) instead of $.$ (I can't find the reference,
though), so we can presume that $.$ is used much more often.  Hence, I
don't think we will fix this inconsistency, and therefore I'm closing
this report.

Best, Arash
