How SshCommand keep its Session State LIKE teminal

void Main()
{
	var host = "127.0.0.1";
	var port = 5022;
	var username = "root";
	var password = "toor";

	using var ssh = new SshClient(host, port, username, password);
	if (!ssh.IsConnected)
	{
		ssh.Connect();
	}
	Console.WriteLine(ssh.RunCommand("pwd").Result.Trim());
	Console.WriteLine(ssh.RunCommand("cd /etc && pwd").Result.Trim());
	Console.WriteLine(ssh.RunCommand("pwd").Result.Trim());

	// using var cmd = ssh.CreateCommand("pwd");
	// var res = cmd.Execute();
	// Console.Write(res);
	// cmd.CommandText = "cd /etc && pwd"; // error CommandText is readonly
}

result:

/root
/etc
/root

expect:
/root
/etc
/etc

Run the supplied C# reproduction and start by tracing SshClient.RunCommand and the command/session behavior it exercises. Done should be demonstrated when the three commands produce /root, /etc, and /etc, with the behavior covered by an appropriate regression test.
