RST nested lists and HTML output

[gjx]

When I convert the following rst file to HTML, I get some weird behavior that doesn't happen when I convert to tex.

Using standard reST nested list syntax, the last item in each block of outer items has ``p`` tags in addition to ``li`` tags.

1. This
2. nested

   a. list
   b. will

3. have
4. *p*
5. tags

If you eliminate the empty lines, then item *b* is loses its ``li`` tag.

1. This
2. nested
   a. list
   b. will
3. skip
4. item
5. *b*

The same thing happens with unordered lists.

* Unordered
* lists

  - also
  - have

* this
* strange
* behavior

The HTML output when I run `pandoc -S -r rst test.rst -o test.html:

<p>Using standard reST nested list syntax, the last item in each block of outer items has <code>p</code> tags in addition to <code>li</code> tags.</p>
<ol style="list-style-type: decimal">
<li>This</li>
<li><p>nested</p>
<ol style="list-style-type: lower-alpha">
<li>list</li>
<li>will</li>
</ol></li>
<li>have</li>
<li><em>p</em></li>
<li><p>tags</p></li>
</ol>
<p>If you eliminate the empty lines, then item <em>b</em> is loses its <code>li</code> tag.</p>
<ol style="list-style-type: decimal">
<li>This</li>
<li>nested
<ol style="list-style-type: lower-alpha">
<li>list</li>
</ol>
b. will</li>
<li>skip</li>
<li>item</li>
<li><em>b</em></li>
</ol>
<p>The same thing happens with unordered lists.</p>
<ul>
<li>Unordered</li>
<li><p>lists</p>
<ul>
<li>also</li>
<li>have</li>
</ul></li>
<li>this</li>
<li>strange</li>
<li><p>behavior</p></li>
</ul>

And the text output:

Using standard reST nested list syntax, the last item in each block of
outer items has \texttt{p} tags in addition to \texttt{li} tags.

\begin{enumerate}
\def\labelenumi{\arabic{enumi}.}
\item
  This
\item
  nested

  \begin{enumerate}
  \def\labelenumii{\alph{enumii}.}
  \itemsep1pt\parskip0pt\parsep0pt
  \item
    list
  \item
    will
  \end{enumerate}
\item
  have
\item
  \emph{p}
\item
  tags
\end{enumerate}

If you eliminate the empty lines, then item \emph{b} is loses its
\texttt{li} tag.

\begin{enumerate}
\def\labelenumi{\arabic{enumi}.}
\itemsep1pt\parskip0pt\parsep0pt
\item
  This
\item
  nested

  \begin{enumerate}
  \def\labelenumii{\alph{enumii}.}
  \itemsep1pt\parskip0pt\parsep0pt
  \item
    list
  \end{enumerate}

  b. will
\item
  skip
\item
  item
\item
  \emph{b}
\end{enumerate}

The same thing happens with unordered lists.

\begin{itemize}
\item
  Unordered
\item
  lists

  \begin{itemize}
  \itemsep1pt\parskip0pt\parsep0pt
  \item
    also
  \item
    have
  \end{itemize}
\item
  this
\item
  strange
\item
  behavior
\end{itemize}
