Random <p> tags inserted when using HTML in markdown

Describe the bug

Random <p> tags inserted when using HTML in markdown

To Reproduce

My markdown also contains html, namely for example

<a href="https://www.goodreads.com/book/show/54774415-glimpses-from-beyond-the-ego">
<img src="../images/post-bcpov6zfbsbr-0.jpg" width="300px" height="auto" alt="Notes from a Dreamer on Dreaming"/>
</a>

When I convert this with markdown2.markdown, I get the following

<p><a href="https://www.goodreads.com/book/show/54774415-glimpses-from-beyond-the-ego"></p>

<p><img src="../images/post-bcpov6zfbsbr-0.jpg" width="300px" height="auto" alt="Notes from a Dreamer on Dreaming"/></p>

<p></a></p>

Which is no longer valid HTML.

Expected behavior

I would expect that section to be ignored by the parser, since it's already HTML. It should just return the same thing.
