Steps to reproduce the issue

1. echo echo aha | podman run --rm -it registry.fedoraproject.org/fedora-toolbox:40 bash -x
2. observe (the ^C is me pressing ctrl-c once):

$ echo echo aha | podman run --rm -it registry.fedoraproject.org/fedora-toolbox:40 bash
WARN[0000] The input device is not a TTY. The --tty and --interactive flags might not work properly
echo aha
[root@ed76234e307e /]# echo aha
aha
[root@ed76234e307e /]# ^C^C
[root@ed76234e307e /]#

3. podman kill -l the container in another shell to get the original shell back

Hi. I was able to reproduce your case, but I was also able to run what you intended.
Check it out:

echo "echo aha" | podman run --interactive docker.io/busybox ash -x

My output:

[giuseppe]

you are passing a pipe as stdin, but requesting to create a terminal. Podman warns you WARN[0000] The input device is not a TTY. The --tty and --interactive flags might not work properly.

Just drop the -t from the command or do not use a pipe as stdin
