Description

Whenever you have centered heading (==<center>Heading</center>==), then it somehow changes following tags in HTML so that they contain <span class="mw-headline" id="Heading">(usual text)</span> that they shouldn't. In case of unordered list (ordered list works the same as other tags) this causes insetion of <li style="list-style-type: none; list-style-image: none; list-style-position: outside;"><span class="mw-headline" id="Heading"></span></li> after every item. This probably shouldn't be visible, but Internet Expolorer seems to ignore that style and so shows an empty list item after every normal item.

Example:

==<center>Heading</center>==

* foo

is rendered as:

<h2><span class="mw-headline" id="Heading"></span></h2>
<center>
<h2>Heading</h2>
</center>
<ul>
<li><span class="mw-headline" id="Heading">foo</span></li>
<li style="list-style-type: none; list-style-image: none; list-style-position: outside;"><span class="mw-headline" id="Heading"></span></li>
</ul>

Probably worth noting that the page in question is:

And that the heading markup is used in a table.

So far I've been unable to reproduce this in a local installation. Seems like a Tidy-related bug (which I can't get working locally).

This looks like a Tidy quirk/bug to me.

The Remex output is

<h2>
<span class="mw-headline" id="Heading"><center>Heading</center></span>
<span class="mw-editsection"><span class="mw-editsection-bracket">[</span>
  <a href="/w/index.php?title=User:Izno&amp;action=edit&amp;section=4" title="Edit section: Heading">edit</a>
  <span class="mw-editsection-bracket">]</span>
</span>
</h2>
<ul>
<li>foo</li>
</ul>

This is not reproducible with RemexHtml. So, closing as resolved.

Izno beat me to it. :)

:D I've been Tidying the Tidy project tasks.
