For some reason, doing `super().forward()` uses it's own input_types but not the super() module's input_types > For some reason, doing `super().forward()` uses it's own input_types but not the super() module's input_types

That's expected. super().forward() is just calling super()'s method instead of overridden one, but your object is still of derived class and resolution of all method calls from within forward() will not change.
