compose: docker-compose V2 fails for port range and replicas>1 where V1 would succeed

Description

Using multiple replicas of a container where each replica should use one of the ports selected by a port-range:

version: "3.4"
services:
  dummy:
    image: busybox
    command: ["sh", "-c", "while true ; do sleep 3 ; date ; done"]
    deploy:
      replicas: 2
    ports: 
      - "6005-6015:5000"

When starting up these containers with docker-compose V1 the container instances use port-mapping where each container picks one host-port from the selected port range to map to internal container port.

$ docker-compose ps
            Name                          Command               State                    Ports
----------------------------------------------------------------------------------------------------------------
docker-compose-issue_dummy_1   sh -c while true ; do slee ...   Up      0.0.0.0:6007->5000/tcp,:::6007->5000/tcp
docker-compose-issue_dummy_2   sh -c while true ; do slee ...   Up      0.0.0.0:6008->5000/tcp,:::6008->5000/tcp

When starting up these containers with docker-compose V2 the containers use all ports from the selected port range to map to internal container port, resulting in error like the following for the second instance of that service:

Error response from daemon: driver failed programming external connectivity on endpoint docker-compose-issue_dummy_1 (6d9cff4937b3b6946e0bb949a36362cf91477f841be34ac9bd2693453b6e8837): Bind for 0.0.0.0:6009 failed: port is already allocated

Steps to reproduce the issue:

1. Switch to docker-compose V1, docker-compose disable-v2
2. Startup containers, docker-compose up -d
3. List running containers and the port mapping they use, docker-compose ps
4. Shutdown service, docker-compose down
5. Switch to docker-compose V2, docker-compose enable-v2
6. Startup containers, docker-compose up -d
7. docker-compose fails to startup because of port mapping clash

Describe the results you received:

docker-compose.yaml only seems to work for V1 and not V2.

Describe the results you expected:

I would expect that docker-compose.yaml can be run by V1 and V2 alike.
