Reloading the last saved state no longer works

Hi there @apogi @doekenorg

Nice plugin but I just wanted to note that reloading the last saved state is no longer working due to chrome deprecating DOMSubtreeModified: https://developer.chrome.com/blog/mutation-events-deprecation

It would be amazing if an update to this was possible!

Cheers,

        $list.on('DOMSubtreeModified', function () {
if (!updating) {
// Prevent endless loop. If we aren't updating don't trigger this event.
return;
}
// If the list is empty, we wait for it to fill up.
if ($list.find('li').length > 0) {
updating = false;
setListOrder($export_form.val(), $list);
}
});
