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. 1616667 1 emilio 2020-02-09 06:36:51 -0800 Err, apparently https://drafts.csswg.org/css-images-4/#valdef-conic-gradient-angle does mention unitless zero. Oh well, kinda unfortunate.
