Vertical scrolling (or visibleItemsInvalidationHandler) resets the inner offset of the orthogonal section with groupPagingCentered

I did UICollectionViewCompositionalLayout with orthogonal section with groupPagingCentered as follow:
Code Block
func neighborsRealitiesSection() -> NSCollectionLayoutSection {
let itemSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1), heightDimension: .fractionalHeight(1))
let item = NSCollectionLayoutItem(layoutSize: itemSize)
let cellWidth = UIScreen.main.bounds.width / 3 + 1
let groupSize = NSCollectionLayoutSize(widthDimension: .absolute(cellWidth), heightDimension: .absolute(cellWidth))
let group = NSCollectionLayoutGroup.vertical(layoutSize: groupSize, subitems: [item])
let section = NSCollectionLayoutSection(group: group)
section.orthogonalScrollingBehavior = .groupPagingCentered
section.visibleItemsInvalidationHandler = { items, offset, environment in
items.filter { $0.representedElementKind != UICollectionView.elementKindSectionHeader }.forEach { item in
let distanceFromCenter = abs((item.frame.midX - offset.x) - environment.container.contentSize.width / 2.0)
let minScale: CGFloat = 0.7
let maxScale: CGFloat = 1
let scale = max(maxScale - (distanceFromCenter / environment.container.contentSize.width), minScale)
item.transform = CGAffineTransform(scale: scale)
}
}
}

The other sections are scrolled vertically. When scrolling vertically, the orthogonal offset is reset to zero. If I comment on the visibleItemsInvalidationHandler, it will not be reset.

Why does it happen? Does anybody have this problem?
