Indeed one modified line is missing in "2.". In function zoom(root, p), you should also add a line after path = path.data(partition ... .key; });:

        path = path.data(partition.nodes(root).slice(1), function (d) {
            return d.key;
        });

        text = text.data(partition.nodes(root).slice(1), function (d) {
            return d.key;
        });
