Actual Behavior

Our application is upgrading from openapi-core v0.14.5 to v0.18.0. We previously specified a custom wkt formatter by setting self.request_validator in our class that inherits from FlaskOpenAPIView, see https://github.com/ASFHyP3/hyp3/blob/develop/apps/api/src/hyp3_api/routes.py#L173

It appears that FlaskOpenAPIView no longer uses self.request_validator in it's dispatch_request method: https://github.com/python-openapi/openapi-core/blob/master/openapi_core/contrib/flask/views.py#L21

Is there an alternate way to specify a custom formatter when using this integration pattern?
