[css-transforms-2] Should individual transform properties accept unitless 0 angle as a value? #2116
Description
Right now they don't per spec.
This came up over https://bugzilla.mozilla.org/show_bug.cgi?id=1207734.
@birtles seemed to think it was good for consistency. I tend to agree, but I also dislike having to add yet another exception to that rule, so I don't have any strong opinion.
Chromium's impl doesn't allow it.
