Potential issue with parsing offsets

[FlyingDR]

There is an issue with offsets parser in a case if part of offset definition is came from map-get()

$map: (offset: 0 1);
.test {
    @include offset(p map-get($map, offset));
}

Expected result:

.test {
  padding: 0 20px;
}

Actual result:

.test {
  padding: 0 20px 0 20px 0 20px 0 20px;
}

Passing of additional flags as options fixes issue:

@include offset(map-get($map, offset), p);
