Child pipeline is not triggered if job in previous stage is retried

Summary

My pipeline contains multiple stages, the trigger of child pipeline is in the last stage, the minimal example is (here)[ https://gitlab.com/mcyprian/paret_child]. In case some of the jobs in the first stage fail/get stuck and it's retried manually, the child pipeline is not triggered and the only workaround is to retry the whole pipeline.

Steps to reproduce

1. run the master pipeline: https://gitlab.com/mcyprian/paret_child/pipelines/new
2. cancel first_job before it's finished
3. retry first_job
