Resolution Note:
Within the project a custom script is adding new additional objects to the Tilemap which are not registered with the undo system.
Extensions to the Tilemap system outside the Tilemap editing ecosystem such as those in the example project should implement editor Undo themselves in their system.
Any change to the Tilemap such as child objects created with Instantiate, added via SetParent, destroyed via DestroyImmediate etc should be registered with the Undo System using their undoable counterpart https://docs.unity3d.com/ScriptReference/Undo.html.
