[BUG] Inconsistency when running $ docker compose -p <project_name> down <list_services>

[jefersoonaf]

Description

When running the command $ docker compose -p <project_name> down <list_services> , it removes all services created with the same <project_name> when it does not find any service that was informed in <list_services>.

Steps To Reproduce

Assuming I have two docker-compose.yml files in different directories:
/app1/docker-compose.yml with services: app1, nginx_app1:

services:
  app1:
    image: app1
    expose:
      - "80"
  nginx_app1:
    image: nginx
    ports:
      - "8080:8080"

/app2/docker-compose.yml with services: app2, nginx_app2:

services:
  app2:
    image: app2
    expose:
      - "80"
  nginx_app2:
    image: nginx
    ports:
      - "8081:8081"

And I performed the up of them separately but using the same project_name:

$ cd /app1
$ docker compose -p myproject up -d app1 nginx_app1

$ cd /app2
$ docker compose -p myproject up -d app2 nginx_app2

After that, if I run:

$ docker compose -p myproject ps

I will see all 4 services running.

And if I want to stop only the services of app1, I can naturally do:

$ cd /app1
$ docker compose -p myproject down app1 nginx_app1

However, this works at first because there were services running with the names app1 and nginx_app1, but if I run this same command a second time, docker ends the services of app2. Why? Since I explicitly informed the services of app1 in the command?

I only noticed that this happens when the command no longer finds any services related to app1 running. But in this case, the expected behavior would be for docker to inform that it did not find any services with the names informed for them to be stopped.
