#247 element is its own parent

[Justin Patterson]

I came across something that looked like this on the Internet: <a href="..."/><img src="..."/></a>. Note that the a tag is closed twice. The HTML parser creates a document where the tag's parent is itself. This seems bad. It caused an infinite loop in my program where I'm trying to see if it's contained in a particular element.

JUnit test attached.
