Consider a model with some properties and one fragment array of objects. Before saving the owner model, object is added to the fragment array with values of object in state A. Then after saving the owner model, server's response is expected to move the individual object property values of fragment arrays to state B. But, in this beta version, the state B after normalizeResponse is ignored and state A is maintained. (Ember - 3.16.8, Ember-data - 3.16.6 )
