I am having trouble understanding how short captions are supposed to work. Consider this org document:
#+begin_src org
,#+title: Short Caption Test
,#+author: Org User
,#+label: table1
,#+caption[This is table1]: And here go on at length in a longer caption.
| Name | Favorite Number |
|------+-----------------|
| Sue | 42 |
| Tom | 99 |
,#+label: table2
,#+caption[This is table2]: But *with* /this/ table, the /short/ caption is *lost*.
| Name | Favorite Color |
|-------+----------------|
| Alice | Red |
| Bob | Also Red |
,#+label: table3
,#+caption[This is table3]: No org markup is used in this long caption, but some $\LaTeX$ is!
| Number | Favorite Person |
|--------+-----------------|
| 0 | Zed |
| 1 | Solo |
#+end_src
When I export it as a LaTeX file, the captions are:
#+begin_src latex
\caption[This is table1]{\label{table1}And here go on at length in a longer caption.}
#+end_src
#+begin_src latex
\caption[\textbf{lost}]{\label{table2}But \textbf{with} \emph{this} table, the \emph{short} caption is \textbf{lost}.}
#+end_src
and
#+begin_src latex
\caption{\label{table3}No org markup is used in this long caption, but some \(\LaTeX\) is!}
#+end_src
The first matches my expectations. The second is an example of taking the last bit of markup as the short caption. The third seems to lose the short caption altogether.
When I look at
#+begin_src emacs-lisp
(org-element-map
(org-element-parse-buffer)
'table
(lambda (x) (org-element-property :caption x)))
#+end_src
Only the first caption seems to have the short caption in the parse results at all. Is this a bug, or should I avoid using markup in captions?
Thank you,
Anthony
#+begin_src emacs-lisp
(org-version)
#+end_src

I can confirm (with a slightly out of date org) this behaviour which
does seem to be inconsistent and/or wrong. However, I wasn't able to
find any discussion of short captions in the org manual so I'm not sure
if there are caveats on their use.

They are described in section 12.8 Captions <https://orgmode.org/manual/Captions.html#Captions>
I think this patch fixes the issue:

Hi Anthony,
I applied a slightly different fix (just moving save-match-data down
the s-expression). Thanks for reporting this and for the fix!

Thanks. Missed that. I was looking in the LaTeX export section of the
manual which doesn't mention short captions! And, actually, the
:caption option for tables, say, doesn't seem to support such?
