ParentNode::$children returns a HTMLCollection of all directly descendant child elements of a container. I had to move around some properties such that the ParentNode property offsets are always at a fixed offset, to simplify the code. This also adds the necessary code to deal with GC cycles in HTMLCollections. Furthermore, we also disable cloning a HTMLCollection as that never worked and furthermore it also conflicts with the [[SameObject]] WebIDL requirement of $children.
