Description
There was a flaky test failure in this jenkins run (no longer available) that reported below.
The unexpected thing is, the test does 4 unmerged and 2 merged BCs. The resulting doc as seen below however, only contains 4 BCs - 2 unmerged and 2 merged. They are OK not to be cleaned up, that's the expectation due to dryRun. And the preceding stats must have confirmed no deletion happened in gc(). Except, why are 2 unmerged BCs missing in the output, that's unexpected.
