PR flutter/plugins#4591 was created based on a local branch renew_cirrus_key, and got closed due to merge base branch to main (so all test were aborted).
Then another PR flutter/plugins#4592 was created right after, using the same branch renew_cirrus_key but to base branch master.
Though all tests passed on the second PR, but fluttergithubbot refused to merge this PR by using the aborted test status in the first PR. My guess is the same branch caused confusion when querying the test checks.
Similar case happens on flutter/engine#30186 and flutter/engine#30185
