NumericRangeFilter does not work

[hwalinga]

class MyModel(models.Model):
    region = IntegerRangeField

class MyModelFilter(filters.FilterSet):
    class Meta:
        model = MyModel
        fields = "__all__"
        filter_overrides = {
            IntegerRangeField: {"filter_class": filters.NumericRangeFilter}
        } 

MyModelFilter({"region_min": 50, "region_max": 100}, queryset=MyModel.objects.all()).qs

This works with django_filters as filters but not with rest_framework_filters as filters. The latter does not filter the queryset.
