When sanitizing an HTML string, the node renderer previously interpreted all empty (no children) nodes as being self-closing or void tags. This would result in invalid HTML being rendered in the result. This patch adds the list of valid void HTML5 elements and checks when a no-children node is encountered to see if the tag that is generated should be rendered as self-closing or not.
