Spec (*) explicitly disallows unitless zero length in math functions:

Note: Because <number-token>s are always interpreted as <number>s or
<integer>s, "unitless 0" <length>s aren’t supported in math functions.
That is, 'width: calc(0 + 5px);' is invalid, because it’s trying to
add a <number> to a <length>, even though both 'width: 0;' and
'width: 5px;' are valid.

There are some existing WPT test cases violating this, which are
removed in this patch.
