merge-gatekeeper fails on jobs not present in the PR

[deeno35]

I have a repo where specific tests are triggered based on which files were updated in a PR. On a number of occisions, I notice merge-gatekeeper in a failed state, even though all other tests are green. When I go and inspect the failed list for merge-gatekeeper, it is tests that weren't in the list of tests triggered for this PR. This list of phantom "failed" tests is not the same or consistent.

It's as if there is some leftover state that is from a different merge-gatekeeper run.
