UITableView insert row animation inconsistent with self-sizing cells

I created a live playground below to illustrate the question. When using self-sizing table cells, the insert row animation (bottom-up) is executed differently depending on the size of the last cell. If the last cell is taller than the cell that is about to be inserted, the animation begins too high and thus animates downward (not upward). What is going on here?

class Live: UIViewController {
    private var entries = ["a\na\na", "b\nb\nb", "c\nc\nc", "d\nd\nd", "e\ne\ne", "f"]
    private let newEntries = ["correct\nanimation\nhere", "correct\nanimation\nhere", "incorrect animation", "correct\nanimation\nhere", "incorrect animation", "correct\nanimation\nhere"]
    private let tableView = UITableView()
    
    override func loadView() {
        view = UIView()
        view.backgroundColor = .blue
        
        tableView.dataSource = self
        tableView.delegate = self
        tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 64, right: 0)
        tableView.backgroundColor = .purple
        tableView.translatesAutoresizingMaskIntoConstraints = false
        tableView.register(EntryCell.self, forCellReuseIdentifier: EntryCell.reuseId)
        view.addSubview(tableView)
        tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        tableView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
        tableView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
        tableView.heightAnchor.constraint(equalTo: view.heightAnchor).isActive = true
    }

        for (n, new) in newEntries.enumerated() {

                self.entries.append(new)
                
                self.tableView.performBatchUpdates({
                    self.tableView.insertRows(at: [IndexPath(row: self.entries.count - 1, section: 0)], with: .bottom)

                    if finished {

                        }
                    }
