Reported by Jim Carroll from Mirantis:

terminal 1:
docker run --rm -it --name katatest --runtime io.containerd.kata.v2 alpine
terminal 2:
docker exec -it katatest /bin/sh
everything seems fine.
Until I try to exit the exec session, at which point the following happens:

• the exec’d session hangs (tty is effectively frozen)
• the original docker run session exits
• docker ps shows that no containers are running

I have to kill the exec command still hung in terminal 2 to regain control of that lost soul
