Duplicate item in paginated list

[dvcolomban]

When I fetch a paginated personal list, I sometimes get a duplicate on the boundary.

For example, on the endpoint /users/<user-slug>/lists/<list-id>/items?page=3&limit=50 Titans is returned as the last item of page 2 (limit 50), but also as the first item of page 3 (limit 50)

The issue doesn't occur when the item is not on the boundary of the page:

Nor does it exist in duplicate in the list on trakt.tv:
