Dependencies that share job names with stages are ignored

I recently encountered an issue with the following .gitlab-ci.yml file:

stages:
  - build
  - deploy

build:
  image: maven:3.5.0-jdk-8
  stage: build
  script:
    - mvn package -q
  artifacts:
    paths:
      - target/myapp.jar

deploy_prod:
  image: maven:3.5.0-jdk-8
  stage: deploy
  only:
    - master
  dependencies:
    - build
  environment:
    name: production
    url: https://myapp.com
  script:
    - {{ deploy things }}

deploy_test:
  image: maven:3.5.0-jdk-8
  stage: deploy
  only:
    - test
  dependencies:
    - build
  environment:
    name: test
    url: https://test.myapp.com
  script:
    - {{ deploy things }}

I expected the deploy_prod and deploy_test jobs to download artifacts from the build job. This did not occur. The expected behavior occurred only when I renamed the build job to something else and adjusted the corresponding dependencies. The artifacts then correctly were downloaded into the deploy_x jobs.

I am not sure if this is intentional behavior or not, but it seemed odd to me so I wanted to bring it to someone's attention.

If it is intentional, I can submit a PR to add a warning on the .gitlab-ci.yml reference page about naming issues.
