Issues when converting "*.tex" to "*.html"

[Slookeur]

Dear @tomduck ,
first of all thank you for your pandoc-xnos tools.
I am in the process of converting a tex document to html, and I am facing several issues with figures caption and numbering,
however I must confess that I am not sure that this is the most appropriate place to report them, although in that case I am
pretty sure that you could point me towards the appropriate direction ;-)
So I tried to convert my tex file using:

pandoc --filter pandoc-xnos --mathjax manual.tex --bibliography full-biblio.bib --wrap=none --default-image-extension=png -o manual.html

Then I face 2 issues:

1. Figure ref are found and number in the document, only and only if, the reference appears after that the figure was inserted, note in the HTML data the [my_img] in the first example and the [1.0] in the second one:

Figure \ref{my_img} presents some information.

\begin{figure}[!h]
\hypertarget{my_img}{
\begin{center}
\includegraphics*[width=23cm, keepaspectratio=true]{my-image}
\caption{My legend}\label{overview}
\end{center}}
\end{figure}

Is converted in:

<p>[Fig. <a href="#my_img" data-reference-type="ref" data-reference="my_img">my_img</a>-a] presents some information.</p>

<div id="my_img">
<div align="center">
<figure>
<img src="my-image.png" id="overview" style="width:23cm" alt="My legend" />
<figcaption aria-hidden="true">My legend</figcaption>
</figure>
</div>
</div>

Whereas:

\begin{figure}[!h]
\hypertarget{my_img}{
\begin{center}
\includegraphics*[width=23cm, keepaspectratio=true]{my-image}
\caption{My legend}\label{overview}
\end{center}}
\end{figure}

Figure \ref{my_img} presents some information.

Is converted in:

<div id="my_img">
<div align="center">
<figure>
<img src="my-image.png" id="overview" style="width:23cm" alt="My legend" />
<figcaption aria-hidden="true">My legend</figcaption>
</figure>
</div>
</div>

<p>[Fig. <a href="#my_img" data-reference-type="ref" data-reference="my_img">1.0</a>-a] presents some information.</p>

2. The caption never show numbers, actually the beginning part of the caption, that should be "Figure #num:" (or something close) is always missing (just see above).

Thanks in advance for your help.
Best regards.
