Issue queue cleanup... My apologies for taking so long to get to this issue!!

See #2419335: W3C Error : Element ul not allowed as child of element ul in this context..

Sorry, I know it's unfair to mark the earlier issue as a duplicate of the later issue, but the later one was the one I saw first and fixed...
