The method insertBefore inserts the node newChild before the existing child node refChild.
If refChild is null, insert newChild at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same
order, before refChild.
Using insertBefore on this Document node attempt to insert a new DocumentFragment node
before a Comment node and verify the contents of the Comment node that is a child
of the DocumentFragment.
