I know you jest, but I don't think that's a good example of "contrast" between the engines. That was just a bug/oversight and fixed in a couple of weeks after it was reported [1].

Actually, it was reported about a year ago by the Dart team: https://bugs.webkit.org/show_bug.cgi?id=199866.

It was an excellent bug report, complete with a reproducible example.

Only after it recently made the rounds on Twitter and hn was it fixed.
