[O] [odt] regression in using an equation sourced via latex_header

[Myles English]

Hello,

If I have a latex file mystyle.tex that contains:

\newcommand{\myBigEquation}{b=23}

and then have this in my org file:

#+LATEX_HEADER: \usepackage{/path/to/mystyle}

I can use it conveniently like this:

\begin{equation}
     \myBigEquation
\end{equation}

and that exports fine to pdf but not to odt.  I am fairly sure it used
to work (around 7th Oct).  Can anyone confirm this?
