`Ctrl-C` no longer terminates `docker compose logs -f` after a `Ctrl-Z` is sent
Description
After sending docker compose logs -f a Ctrl-Z to try and suspend the process, the process is no longer cancelable using Ctrl-C, and can only be terminated by sending a SIGKILL (signal 9) signal, as SIGTERM (signal 15) nor SIGQUIT (signal 3) cause the process to terminate either.
Steps to reproduce the issue:
docker compose logs -f- Press
Ctrl-Z - Press
Ctrl-Cone or more times.
Describe the results you received:
Sadness and disappointment that the docker compose logs -f refuses to terminate.
Describe the results you expected:
docker compose logs -f terminates.
Additional information you deem important (e.g. issue happens only occasionally):
Sending the default SIGTERM (signal 15) signal to the process doesn't cause it to terminate, nor sending a SIGQUIT (signal 3), either. Only sending a SIGKILL (signal 9) does.
It appears that proper signal handling seems to be a persistent problem for the docker-compose tool:
- CTRL-C does not end compose logs -f #8880
- Regression on compose logs -f frozen wrt Ctrl-C #8977
- (Regression) Pressing CTRL+C on docker-compose up hangs when using containers with restart: unless-stopped|always #9003

I am experiencing a potentially similar(?) issue on a fresh (2 days old) installation of Docker on Ubuntu 22.04 (installation method). Unlike on my other identical deployments, docker compose logs -f [service] on this server requires three ^C presses to terminate, every time. Regardless of whether I press ^Z or not.

I am using the fish shell, but it happens if I change my shell to /bin/bash and /bin/sh too. I am using Windows Terminal, but it happens if I use OpenSSH in mingw (git bash) too. It may also be #8880 that I'm seeing.
For me this is fixed in the latest release https://github.com/docker/compose/releases/tag/v2.14.2, by commit 7cf6d5ec4eadc3a991d84c4df43fb7c7a70943cc.
