Improperly parsing HTML

[tlindsay]

In the first paragraph of this article, the author includes a small <code> block:

<code class="cw np nq nr ns b"><marquee></code>

When rendering this article via libmedium, the parser doesn't realize that the <marquee> is supposed to be the text-literal contents of the <code> block, and instead treats it as an unclosed part of the document. This causes the rest of the article to render inside of
the <code><marquee>... which is... not ideal for readability 😆
