Comment (by gigelu):
Digging deeper, I found something interesting here:
https://github.com/django/django/blob/master/django/core/paginator.py#L69

If I change the `@cached_property` to `@property`, it is called 5 times
and only the first time it shows `[1, 5]`, the other 4 times it shows `[5,
5]`.
Nonetheless, if I remove the breakpoint it returns only one notification.
If I change the order in the list, `[len(self.object_list),
self.object_list.count()]` it shows every time `[5, 5]`.
