FacetedFilterSearchFilterBackend not working when filtering using "__in" operator

[gmuj]

Describe the bug

When using filter with in operator and facet param eg:
?facet=state&state__in=published__not_published

I get the following error:

    def aggregate(self, request, queryset, view):
>       facets = queryset._facets
E       AttributeError: 'Search' object has no attribute '_facets'

Environment

Which version of Elasticsearch are you using?

To Reproduce
Steps to reproduce the behavior:

Add the following test to django_elasticsearch_dsl_drf/tests/test_faceted_filtered_search.py

    def test_list_results_facet_and_filter_using_in_operator(self):
        self.authenticate()
        url = reverse('bookdocument_faceted_filtered-list')

        response = self.client.get(url + '?facet=state&state__in={}__{}'.format(
            constants.BOOK_PUBLISHING_STATUS_PUBLISHED,
            constants.BOOK_PUBLISHING_STATUS_NOT_PUBLISHED
        ))
        self.assertEqual(response.status_code, status.HTTP_200_OK)

        # Should contain all published books
        self.assertEqual(len(response.data['results']), self.published_count)

        # Should contain 1 facet
        self.assertEqual(len(response.data['facets']), 1)
        self.assertEqual(response.data['facets']['_filter_state']['state']['buckets'], [{
            "doc_count": self.published_count,
            "key": "published"
        }, {
            "doc_count": self.not_published_count,
            "key": "not_published"
        }])

Expected behavior
No error should happen.
