Powershell Subsystem Fails when using a banner in OpenSSH

Using a Banner option within sshd_config causes the connection to fail

Banner /etc/ssh/banner

If we comment out the Banner line, and restart sshd, client connections work just fine.

Steps to reproduce

PS /Users/drewstinnett> Enter-PSSession -Host host.example.com -SSHTransport -UserName drews
Enter-PSSession : The background process reported an error with the following message: The SSH client session has ended with error message:
####
# Example Banner
####
At line:1 char:1
+ Enter-PSSession -Host host.example.com -SSHTransport -UserNam ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ResourceUnavailable: (:) [Enter-PSSession], PSRemotingTransportException
    + FullyQualifiedErrorId : System.Management.Automation.Remoting.PSRemotingDataStructureException,Microsoft.PowerShell.Commands.EnterPSSessionCommand

PS /Users/drewstinnett>

Expected behavior

PS /Users/drewstinnett> Enter-PSSession -Host host.example.com -SSHTransport -UserName drews
####
# Example Banner
####
[host.example.com]: PS /home/drews>

Actual behavior

PS /Users/drewstinnett> Enter-PSSession -Host host.example.com -SSHTransport -UserName drews
Enter-PSSession : The background process reported an error with the following message: The SSH client session has ended with error message:
####
# Example Banner

Is this issue going to be investigated?If a banner is used (for example in corporate environments with a legal statement before connecting to a linux machine) , you need a windows machine for powershell remoting to other linux machines.
