The last page of the first collection is only loaded into memory when it is being viewed. If it isn't loaded into memory, the `#size` call triggers a count query. This `#count` would generate an invalid query if our custom preloaded counts are included by adding a separate `as count_column` alias on top of the count aliases. Removing the selects in this case will make sure a valid `COUNT(*)` is generated.
