When connecting to a remote host for the first time, ssh notices that the server has not yet been added to known_hosts. Hence it shows a warning saying "The authenticity of host 'whatever' can't be established", followed by the fingerprint and asks "Are you sure you want to continue connecting?". Core Shell redirects all of this to a separate dialog box, and most of the time, this works fine.
Sometimes however, and I haven't been able to figure out when exactly, Core Shell truncates the information to a generic "Input Required" dialog showing only the possible answers:
The problem is that when this happens, the user has no context whatsoever about what triggered the input because the dialog is missing the original terminal message as well as the (in some cases critical) key fingerprint.
