Summary conic-gradient() incorrectly accepts unitless zero angles

Safari accepts `document.body.style.backgroundImage = "conic-gradient(yellow 0, blue 360deg)"` and so on. I think that's invalid per spec. I don't see anything in https://drafts.csswg.org/css-images-4/#funcdef-conic-gradient which would say that zero is a valid angle value in this context. See https://bugs.chromium.org/p/chromium/issues/detail?id=1050395 too.

Err, apparently https://drafts.csswg.org/css-images-4/#valdef-conic-gradient-angle does mention unitless zero. Oh well, kinda unfortunate.
