Paramiko SSH Banner Error

I am trying to use ansible + network_cli connection type to connect to a cisco IOS device through a linux bastion host. Below is the ssh route:

linux --> linux --> network_device

I've noticed that the ssh banner returned when manually using the ssh -o ProxyCommand="ssh -W %h:%p @ -p <bastion_port>" <device_username>@<device_ip> might be confusing paramiko. SSH Banner returned:

The end of the banner and the password prompt seem to be on the same line, which I believe is causing ansible to return a "Error reading protocol banner" when trying to run with network_cli (which uses paramiko and ignores any ssh_config file parameters). How would I go about adding a newline to the returned banner so the prompt wont confuse paramiko, if that is a possible issue?

Start by reproducing the Ansible network_cli connection through the Linux bastion with the shown ProxyCommand, then inspect Paramiko's protocol-banner handling around the reported "Error reading protocol banner." Done means determining whether the Cisco IOSv banner formatting triggers the error and documenting or correcting the supported behavior.
