Last item in a list named as a CSS property

[sandrojohanides]

Seems to happen in a comma separated list when a string is named as a CSS property (bottom, color...). In a space separated list, all of the property-like strings are incorrectly highlighted. Doesn’t work for all properties, see position.

@if index((top, bottom), $dir) {
    $offset-dir: if($offset-dir == right, right, left);
} @else if index((left, right), $dir) {
    $offset-dir: if($offset-dir == bottom, bottom, top);
}
