Figure label becomes part of the text

[larsga]

I have the following LaTeX source:

\begin{figure}
\begin{center}
\includegraphics[width=11cm]{photos/salaus-alus.jpg}
\end{center}
\caption{Kupi\v{s}kio Salaus Alus}\label{fig:salaus-alus}
\end{figure}

which turns into

<div class="figure">
<img src="media/file0.jpg" alt="Kupiškio Salaus Alus" /><p class="caption">Kupiškio Salaus Alus</p>
</div>
<p>[fig:salaus-alus]</p>

in the epub output. The problem here is that the label becomes part of the output text. That last <p> really shouldn't be there at all.

\ref and \label don't seem to be supported by Pandoc at all. There are a bunch of workarounds using filters described in #813, as well as some background information on that design decision.

As for why they're rendered in braces, my best guess is to provide the breadcrumbs, so a reader can manually trace references back to their definitions.

The relevant lines seems to be 415, 416 in Readers/LaTeX.hs, in the current HEAD.

The original intent of the braces was to provide some trace in the file so you can reconstruct references. But I thin there are two ways this could be improved. First, we could parse a \label after a caption as part of the inline contents of the caption, rather than a new block. Second, we could make this a Span element with no contents, so it doesn't produce any visible text in the output, but still gives a trace that could be manipulated into something more useful.
