Dependent service not working correctly when defined via `extends`

[thisismydesign]

Description of the issue

I have a docker-compose file that starts a few services from different repos. The repos are also standalone with their own docker-compose files so I want to reuse that. I ended up with:

services:
  elasticsearch:
    extends:
      file: ../other-service/docker-compose.yml
      service: elasticsearch

  web:
    extends:
      file: ../other-service/docker-compose.common.yml
      service: web
    build:
      context: ../other-service
    depends_on:
      - elasticsearch

Then when I do dc up web I see both services correctly creating but there are no logs from elasticsearch. Further, when I ctrl+c out of the process, it only closes the web service. Using docker ps I still see elasticsearch runnnig and I have to do dc down to stop it.

If I define the elasticsearch service in place (exactly the same definition as in the other file) it works perfectly. The service definition is a basic out-of-the-box one:

  elasticsearch:
    image: elasticsearch:6.5.4
    environment:
      - ...
    ports:
      - ...

I think this was caused by starting a specific service, in which case dependencies start in the background. This is annoying but doesn't have to do with extends
