Issue Summary

When multiple pipeline builds are triggered upon the creation of a pull request using the trigger-pipeline pipe in parallel, only the initial PR build and the first triggered build are displayed in the PR

Steps to Reproduce

1. Create three parallel pipeline steps using the trigger-pipeline pipe. Set them to start when a pull request (PR) is created and trigger custom steps.
2. Define three different custom steps for your pipeline.
3. Create a PR
4. The PR will trigger the initial build and three additional builds via the parallel steps for custom steps.
   

Expected Results

Pull requests show all pipelines that were triggered on the same commit in the list.

Actual Results

Pull requests only show the initial build and the first build from 3 custom steps in the list.

Workaround

No workaround at this moment. Will add it here if we have it in the future.
