This worries me. I'm not saying this is right or wrong, but as a frequent breaker of test expectations, I'd like to understand this weird behavior in the event that this expectation changes with a future patch. Could you help us understand why this happens a little better, then maybe explicitly call it out in the changelog or explain it here and provide a link to this bug in the test?
