Keeping the test is excellent, because it gives us a way to confirm that a second attempt at a fix is at least as good as the first. The only thing that could improve this situation is to add a test that checks the bug that the previous version introduced, so that the next round doesn't repeat the mistake. That can be deferred because it is more important that we get this fix in time for the next release candidate. Thanks, -Stolee
