Propagation

When an admin updates an editable element in the template (i.e. content-three-columns template), those changes need to propagate to all editable elements that originated from this template. However, the content of dependent editable elements should not be overridden.
Can you iterate over an array of items [4,5,6] for this test? It looks like you have the same test, just with the number of elements interchanged.
