[Orgmode] Figure caption containing math mode not typeset

[Ahmed Fasih]

Hello, I have a figure with a caption that contains dollar signs to
typeset math mode:

  #+CAPTION:    Approximating ... for $s(y_0) = \exp(j k_y y_0)$.
  #+LABEL:      fig-mylabel
  #+ATTR_LaTeX: width=0.9\textwidth placement=[t]
  [[file:figs/myfile.pdf]]

When this is converted to PDF via pdflatex (C-c C-e d), the math in
the caption is not correctly formatted because org-mode escapes the
dollar signs: in the generated .tex file:

  \caption{\label{fig-mylabel}Approximating ... for \$s(y$_0$) =
$\exp$(j k$_y$ y$_0$)\$.}

Elsewhere in my org file, the dollar signs work perfectly, typesetting
math as expected. I would expect the math in the org file's caption to
be copied verbatim to the Latex figure's caption.

I believe I'm using the latest org-mode but an older Emacs. Advice is
much appreciated. Thank you for an incredible tool,

Ahmed
