Pipeline view shows incorrect jobs

Summary

Steps to reproduce

What is the current bug behavior?

Incorrect pipeline jobs are shown

What is the expected correct behavior?

Correct pipeline jobs are shown

Relevant logs and/or screenshots

Below are screenshots showing the behavior of the bug, essentially the pipeline view shows incorrect information entirely for the pipeline 2085925605 view. If you view the MR the pipeline was created from it references the expected jobs/commit/branch in the modal. The problem arises in the specific pipeline view for 2085925605, which shows all incorrect information from 2019.
