Child Pipeline ignoreing Jobs without Rules

Summary

When triggering a child pipeline, the jobs which have no rule assigned are skipped.

Steps to reproduce

Create basic pipeline. Trigger Child pipeline in file (same repo is easiest)

Example Project

Private repo used.

stages:
  - prepare

.triggerPipeline:
  stage: prepare
  trigger:
    include:
      - ci/.someOtherFile.yml
    strategy: depend
    forward:
      pipeline_variables: true
      yaml_variables: true
  
ActualJob: 
  extends: .triggerPipeline
  rules:
    - if: $CI_PIPELINE_SOURCE == $CI_PIPELINE_SOURCE
      when: always

.someOtherFile.yml

iamskipped:
  script:
    - echo "Oh look I don't exist"
iamalsoskipped:
  script:
    - echo "Oh look I don't exist"
  when: always
irun:
  script:
    - echo "Oh look I exist"
  rules:
    - if: $CI_PIPELINE_SOURCE == $CI_PIPELINE_SOURCE
      when: always
