Unable to expand upstream and downstream pipelines after upgrading to 11.8

Summary

After updating to 11.8, we are no longer able to expand the Upstream and Downstream pipelines inline and not able to open pipeline in new tab.

Steps to reproduce

  1. Create a project with .gitlab-ci.yml that triggers a downstream pipeline
  2. Create another project with .gitlab-ci.yml to be triggered by the upstream pipeline
  3. Kick off the pipeline in the upstream project
  4. Navigate to the pipelines page

What is the current bug behavior?

Unable to expand the upstream or downstream pipelines

What is the expected correct behavior?

Upstream and downstream pipelines are expanded inline and opened in a separate tab.

Relevant logs and/or screenshots

This is thrown in the deveopler console when clicking the Downstream pipeline. Downstream-console-error

Nothing happens when clicking the Upstream pipeline.
