@turf/kinks and @turf/unkink-polygon

The kinks package detects self-intersection in the following shape: https://gist.github.com/polizz/53bfb5d8cd0e7cac09ae6543e1c89528. When I run the shape through unkink-polygon, I get the same shape back out. Not sure what is wrong here. The unkink-polygon function does work on other self-intersecting polygons. Let me know if I can provide more information.

export function removeDuplicatesAndFormatGeoJson(wkt) {
  try {
    let cleanGeom = clean(parse(wkt));
    const hasKinks = get(kinks(cleanGeom), 'features[0].geometry', false);

    if (hasKinks) {
      const unkinked = unkink(cleanGeom);
...

Start by reproducing the supplied shape from the gist through the @turf/kinks and @turf/unkink-polygon entry points. Inspect how the two packages handle this self-intersection and compare it with the other self-intersecting polygons that already work; done means the supplied shape is correctly unkinked without regressing those cases.
