  const collapsed = rng.collapsed, normRng = rng.cloneRange();
  const startPos = CaretPosition.fromRangeStart(rng);

  normalizeEndPoint(dom, collapsed, true, normRng).each(function (pos) {
    // #TINY-1595: Do not move the caret to previous line
    if (!collapsed || !CaretPosition.isAbove(startPos, pos)) {
      normRng.setStart(pos.container(), pos.offset());
    }
  });

  if (!collapsed) {
    normalizeEndPoint(dom, collapsed, false, normRng).each(function (pos) {

  // If it was collapsed then make sure it still is
  if (collapsed) {
    normRng.collapse(true);
  }

  return RangeCompare.isEq(rng, normRng) ? Option.none() : Option.some(normRng);
