proposedNewDestinationRow()

[tuant2n]

Hi, I dont know why need to + 5pixel in here
`let visibleCells = tableView.visibleCells.filter {
// Workaround for an iOS 11 bug.

        // When adding a row using UITableView.insertRows(...), if the new
        // row's frame will be partially or fully outside the table view's
        // bounds, and the new row is not the first row in the table view,
        // it's inserted without animation.
        
        let cellOverlapsTopBounds = $0.frame.minY < tableView.bounds.minY **+ 5**
        let cellIsFirstCell = tableView.indexPath(for: $0) == IndexPath(row: 0, section: 0)
        
        return !cellOverlapsTopBounds || cellIsFirstCell
    }`

It creates a crash when I have 2 section, section 0 is empty, section 1 have 2 rows and visibleCells only have a cell at Index(1, 2)
