[css-transforms-2] scale property behavior differs from scale() function #2109
Description
This is basically just re-opening issue #856 but without the focus being interop.
transform: scale(2)
is equivalent to transform: scale(2, 2), i.e. scaling both x/y.
scale: 2
is equivalent to transform: scale(2, 1), i.e. scaling x only.
That seems inconsistent and surprising. I've yet to meet anyone who expects that scale: 2 scales in only x.
I understand that scale can be used for 3D transforms, but scale3d() requires three arguments so I don't think there's any parallel between the arguments used there and here.
