Ah thanks, I missed it. So this means that

   flex: 1px 1 2

is allowed but

   flex: 0 1 2 (where 0 is the flex basis)

is not. I understand we don't have an ambiguity in the spec but
honestly, that's not very nice. Can I ask why we just can't forbid
unitless lengths here and make the whole thing simpler? We've always
said in the past that unitless 0 length was tolerated but not
encouraged.
