CodeQL complaints about "Missing call to __init__ during object initialization" in inherited ModelSerializer class.

Code of this example of a DynamicFieldsModelSerializer taken from the docs.

class DynamicFieldsModelSerializer(serializers.ModelSerializer):
    """
    A ModelSerializer that takes an additional `fields` argument that
    controls which fields should be displayed.
    """

    def __init__(self, *args, **kwargs):
        # Don't pass the 'fields' arg up to the superclass
        fields = kwargs.pop('fields', None)

        # Instantiate the superclass normally
        super().__init__(*args, **kwargs)

        if fields is not None:
            # Drop any fields that are not specified in the `fields` argument.
            allowed = set(fields)
            existing = set(self.fields)
            for field_name in existing - allowed:
                self.fields.pop(field_name)

CodeQL complaints about 'Class DynamicFieldsModelSerializer may not be initialized properly as method.Field.__init__ is not called from its __init__ method.

What is the correct way to initialize the base classes here?
Call them (all - BaseSerializer, Field) explicit?
Omit the super() call at all?
