connect_get_namespaced_pod_exec cannot run nohup command and return immediately

[HuanjieGuo]

What happened (please include outputs or screenshots):

Here is the command

    command = ['bash', '/mnt_target/rsync_command.sh']
    res = stream(tess_client.api.connect_get_namespaced_pod_exec,
        pod_name,
        namespace,
        command=command,
        stderr=True,
        stdin=False,
        stdout=True,
        tty=False,
        async_req = False
    )
    return res

cat /mnt_target/rsync_command.sh
nohup rsync -vr /mnt_source/ /mnt_target > /mnt_target/rsync.log 2>&1 && echo 1 > /mnt_target/rsync_done.txt &

when I call connect_get_namespaced_pod_exec, it will block there and cannot return immediately.

What you expected to happen:
It should return immediately because I use nohub &

Is this reproducible with kubectl?
