    Set<ElementLocator> result = Sets.newHashSet(activeRangeLocators);
    Collection<ElementLocator> loc = Sets.newHashSet();
    if (ele instanceof AbstractElement)

    if ((last instanceof AbstractRule && hiddenTokenHelper.isComment((AbstractRule) last)) || (ele instanceof AbstractRule && hiddenTokenHelper.isComment((AbstractRule) ele)))
        loc = collectLocatorsForComments(loc, last, ele);
    last = ele;
    for (ElementLocator locator : loc) if (locator.getType() == LocatorType.RANGE && !activeRangeLocators.add(locator))
