Bug 338707 Reconciler chokes on elements under parents that have been removed from the model

	 * <li>The user renames this part as "customName".</li>
	 * <li>Later, the application changes the name to "name2".</li>
	 * <li>The merged outcome should be that the part stay named as
	 * "customName".</li>
