Integer interpolation should be rounded towards positive infinity.

Currently, interpolation of \<integer> is rounding away from 0.
The interpolation's result should be rounded according to the spec,
https://drafts.csswg.org/css-values-4/#combine-integers, which is

"the result is converted to an \<integer> by rounding
to the nearest integer, with values halfway between
adjacent integers rounded towards positive infinity."
