Rootless containers running through podman-compose cannot access host services

**Describe the bug**
I have just upgraded to Fedora 40, and this has caused a havoc in my rootless podman-compose containers, that were working under Fedora 39. The root of the problem is that host services (e.g. the HTTPS web server running on host) are no longer accessible.

```
$ podman-compose version
podman-compose version 1.2.0
podman version 5.2.2
```

**Environment:**
- OS: Linux / Fedora 40
- podman version: 5.2.2
- podman compose version: 1.2.0

**Additional context**

I have read several bugs reports about podman switching to pasta, and I have tried several approaches proposed (switching to slirp4netns in containers.conf, using pasta with options --map-guest-addr, etc.)

However, these seem to work when I manually run a container with podman run, but not when I run the containers through podman-compose.

Is there a solution to make my containers work again and access host services from them, as before the upgrade to Fedora 40?

I have been looking for more than 3 days for a solution, without success. Under Fedora 39, it worked out of the box, I haven't done anything special. I was accessing the host through its DNS hostname entry.
