mikrotik ssh /terminal/ask

Good day. Thank you for such a good product as windterm.

I ran into some problems in ssh ROS 7.12: when requesting
`/terminal/ask preinput="editme"`
and after moving the cursor, the terminal freezes, not allowing to edit the line and not allowing to interrupt the script

Reproduce the freeze in WindTerm with MikroTik RouterOS 7.12 by running `/terminal/ask preinput="editme"`, moving the cursor, and checking whether editing and interruption still work. Start by tracing the SSH terminal input path; done means the line remains editable after cursor movement and the script can be interrupted.
