UICollectionViewCompositionalLayout doesn't scroll to incomplete group

Question

I have simple implementation with UICollectionViewCompositionalLayout. There are two sections, every has single row with horizontal scroll and every item at section has 1/4 width of whole container (now it's full screen).

I would like to have paging scroll, but when data source provides 4n+1 elements at the section I can't scroll to access last item.

How to fix it with pure animation for last item like with simple UICollectionViewFlowLayout?

func createCollectionViewLayout() -> UICollectionViewLayout {
    UICollectionViewCompositionalLayout { sectionIndex, environment -> NSCollectionLayoutSection? in
        let itemSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1 / 4), heightDimension: .fractionalHeight(1))
        let item = NSCollectionLayoutItem(layoutSize: itemSize)

        let groupSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1), heightDimension: .fractionalWidth(0.4))
        let group = NSCollectionLayoutGroup.horizontal(layoutSize: groupSize, subitem: item, count: 4)

        let headerSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1), heightDimension: .absolute(44))
        let header = NSCollectionLayoutBoundarySupplementaryItem(layoutSize: headerSize, elementKind: UICollectionView.elementKindSectionHeader, alignment: .top)

        let section = NSCollectionLayoutSection(group: group)
        section.orthogonalScrollingBehavior = .groupPaging
        section.boundarySupplementaryItems = [header]

        return section
    }
}

Answer 1

After complex research: seems like layout bug, one possible solution is to change programmatically the orthogonalScrollingBehavior depending on the number of items
