The PRT failure seems to be directly linked to the search issue mentioned in the PR description. So I wonder if the packit setup failed for z-stream (while it worked well in master where the packit/PRT passed) since the Katello fix PR raised against Katello master might fail to be used at z-stream Satellite? Maybe @Griffin-Sullivan could say if it's possible.

Nevertheless, the failing test is expected to keep failing until the fix is merged, backported and delivered downstream. It is not directly related to this PR (apart from the fact that this PR revealed it).
