Re: [csswg-drafts] [css-values-4] `round(line-width, ...)` specification is confusing (#13794)

> Otherwise, identical to nearest, except that if A is positive (non-zero) and one of lower B or upper B is zero, choose the non-zero one, then snap as a border width.

For A>0 and B=0, lower B and upper B are zero? if so then the "non-zero one" does not exist.
