Right now HTMLCollection forwards ref/deref to its owner but this model makes tricky to merge it with DynamicNodeList. Also, we never delete HTMLCollection as long as its owner is alive because no one clears entries in m_cachedCollections, end up consuming a lot of memory over time when the node is left in the tree.
