exp/html: ignore self-closing flag except in SVG and MathML

In HTML content, having a self-closing tag is a parse error unless
the tag would be self-closing anyway (like <img>). The only place a
self-closing tag actually makes a difference is in XML-based foreign
content.

Pass 1 additional test.

LGTM.

I find this surprising, but I shouldn't be: it's HTML5.
