New description:
I have a custom Manager to filter out model instances with where the field
`deleted` is `True`. I'm using an ORM query that looks like
`user1.page_set.filter(membership__user=user2)`.
My expectation is that `Membership` objects with the deleted flag set are
not included in the query. Instead, they are being included.
