docker compose kill command ignores COMPOSE_IGNORE_ORPHANS

[theswordsmahin]

Description
I have several different directories with separate compose files. For each directory, i specify the same COMPOSE_PROJECT_NAME.
Running docker compose down with COMPOSE_IGNORE_ORPHANS=true works as expected and only removes containers for services within the current directory. docker compose kill however removes all other containers that were started.

Steps to reproduce the issue:

1. Make 2 directories, each with a separate docker-compose.yaml file (with different service names) and .env file. Specify the same COMPOSE_PROJECT_NAME and COMPOSE_IGNORE_ORPHANS=true in each .env file
2. Run docker compose up in one directory.
3. Run docker compose kill in the other directory.

Describe the results you received:
Containers started from the first directory are killed.

Describe the results you expected:
Containers from first directory remain running

Additional information you deem important (e.g. issue happens only occasionally):
docker compose down and docker compose rm seem to behave as intended.
