The Graphite UI continues to show checks in a continued run state when pushed multiple times while Github shows them as successful.
The cost: If there are required checks they never resolve until a developer forces them to run again either by re-running them or force pushing. Depending on the workflow- this could be anything from quick CI test to longer e2e test that need to run. This also impacts MWR, PRS just won't auto merge.
This has continued to be a bug for awhile- I've reported it a few months ago and followed up with a link to a PR in our repo that was experiencing this issue. I have 5 PRS in a stack going through this right now.
