You do not deserve to be downvoted. As a developer, I wholeheartedly agree with you (anyone remember Safari's super buggy indexed DB implementation?!)
The downvotes are happening because this would have been as possible to achieve in Safari as in Chrome had the author chosen to develop purely in that, and Chrome would have been one of the engines that look broken. At this level you’re relying on engine quirks rather than spec compatibility.

This is not true.

I think you're misunderstanding - the art was developed with standards. Safari is the piece that is failing the standards, not the art.
