Fix parent child pipeline relationship specs

What does this MR do?

To address flakiness reported in #217250 (closed)

Where the error shows that the element stretched out too far possibly overlapping other elements thus prevent Selenium from perform clicking.

Though I couldn't reproduce this locally, adding a wait on this page seems reasonable as well as move the pipeline status check up before clicking will also give it another tiny window to load.

Leaving the quarantine tags in to monitor behavior for a few days first.
