ce.ProtectedNode doesn't like to be torn down when it's detached, and this was happening to CE nodes created in the MWReferenceList. Hack around this by attaching the CE nodes generated by the MWReferenceList to the ce.MWReferenceListNode (so they have a parent and a way of getting to the surface), and by guarding against multiple successive setups/teardowns in ce.ProtectedNode.
