My App has wrong behavior when I used UICollectionView API - scrollToItemAtIndexPath.( ios15 beta4)

Model : iPhone 12 pro max

System : iOS 15 beta4

Desc : I set the collectionView to scroll to the back of the item, but it actually scrolls to the front. The problem is currently only in iPhone 12pro max.

NSInteger row = indexPath.item + 1; 
if (row > 0 && row < [self.dataSource collectionView:self numberOfItemsInSection:indexPath.section]) {   
     [UIView animateWithDuration:.3 animations:^{       
         [self scrollToItemAtIndexPath:[NSIndexPath    indexPathForRow:row inSection:indexPath.section]   atScrollPosition:UICollectionViewScrollPositionNone  animated:NO];      
      }];
 }
