On iOS, scroll views support "rubber banding", where there is some elasticity when scrolling past the end of the scrollable region. This causes
scrollTopandscrollLeftvalues that are negative, or go beyond the height of the content. This caused CollectionView to shake as it was confused by this, so now we clamp the scroll position to the correct bounds to avoid this.
