There are more coincidences that are even less interesting. But even the above should make it clear how unlikely it was that I found this thing.
Just to be clear: I didn't mean that I didn't do good - I did. I mean that we got unreasonably lucky here, and that we can't just bank on that going forward.
@AndresFreundTec but there are thousands of devs running all sorts of tests. The question is not "what were the odds that you missed it", but "what were the odds that everybody missed it"...
