Section and heading id in MediaWiki output

Section and heading id in MediaWiki output

[BPJ]

When converting to mediawiki MW headings are prepended with a span
`<span id="HEADING-ID"></span>`, evidently to provide an anchor to
pandoc's original/automatic id so that internal links will still work.
However
if there is a `<section>` element[^1] I frequently end up with an identical
id
tag on the div resulting from the section element and the automatically
inserted span element, which seems like a bug to me:

``````html
<section id="head-2" class="level2">
<h2>Head 2</h2>
<section id="head-3" class="level3">
<h3>Head 3</h3>
<ol type="1">
<li><p>Li 1</p></li>
<li><p>Li 2</p>
<p>Li 2 para 2</p></li>
<li><p>Li 3</p></li>
</ol>
<p>Text</p>
<ol type="i">
<li>Li i</li>
<li>Li ii</li>
</ol>
</section>
</section>
``````

``````mediawiki
<div id="head-2" class="section level2">

<span id="head-2"></span>
== Head 2 ==

<div id="head-3" class="section level3">

<span id="head-3"></span>
=== Head 3 ===

<ol style="list-style-type: decimal;">
<li><p>Li 1</p></li>
<li><p>Li 2</p>
<p>Li 2 para 2</p></li>
<li><p>Li 3</p></li></ol>

Text

<ol style="list-style-type: lower-roman;">
<li>Li i</li>
<li>Li ii</li></ol>


</div>

</div>
``````

It seems that the only fix currently is to go through the MW source after
conversion and manually remove any offending spans.

I wish the mediawiki writer were smart enough to not insert the span above
the
heading if its id would be identical to that of a parent section div. Would
that
be possible, and is this enough of a bug to submit an issue?

In the actual use case I modify the HTML input with an HTML editing
script/library before conversion to mediawiki, and as a part of that I add
attributes to the section elements which I want to be there on the div in
the MW output, so removin

[^1]: In my case inserted by pandoc into the HTML now used as source at an
earlier run.
