sshs not working from Mintty on Windows 10?

Hello,

I'm working on Windows 10 x64, and use the Git Bash utility for my CLI needs. This utility can use either the classic cmd of Windows, or Mintty. I always use Mintty instead of the classic Windows cmd.

Unfortunately, sshs does not seem to work in Mintty. It works great in Windows cmd (same behavior as the GIF in the readme file), but here is what I see when ran from Mintty (no output and of course no other window is displayed):

Does anyone else has the same problem? Is sshs incompatible with Mintty or is this a configuration issue on my part?

Thank you for your help!
