Orphans not being added when using CustomPagination

[Strapchay]

I noticed there seems to be no code that enforces the functionality of the orphans while going through the PageNumberPagination code. I had first overriden it using a CustomPagination but that didn't seem to have any effect till i checked the code. I have made some basic modifications to the code to implement this functionality but can anyone else confirm if they also experience this issue before i open an issue .

This is what my code looked like before the modification:

class CustomPagination(PageNumberPagination):
    PER_ROW = 20

    def get_paginated_response(self, data):
        return Response(
            {
                "next": self.get_next_link(),
                "previous": self.get_previous_link(),
                "per_page": self.page_size,
                "count": self.page.paginator.count,
                "results": data,
            }
        )

And the paginator for the specific view:

class ChatPagination(CustomPagination):
    page_size = 30
    page_query_param = "page_query"
    page_size_query_param = "page_size"
    max_page_size = 100
    orphans = 3
