Sorting breaks when $resources isn't an instance of ResourceGridView

[LeanderFS]

Sylius version affected: 1.8.5

Description
When creating a filtered list using the methods described on the documentation page, the sorting breaks because the returned class is an instance of PagerFanta\PagerFanta, which doesn't have a data key as required on line 1 of _sorting.html.twig

Steps to reproduce

1. Create a list using the methods described in the documentation
2. Try to visit the page

Possible Solution
Not a possible solution, but the problem seems to be that resources.data does not exists when $resources is an instance of PagerFanta.
