Description
Using an abstract model which is also an abstract class.
In the subclass, I need to modify a field. This is done in the init_subclass method, by creating a field and adding it to the model with ModelBase.add_to_class.
The field disappears from the class.
Doing exactly the same on a model which is not an abstract class works fine.
