When I drag a node with hidden siblings, the chart breaks! about orgchart HOT 1 OPEN

code below is my fix:

function switchHorizontalArrow($node, isExpand) {
/* fix node with sibling drag begin /
$node.data('bContainsSiblings', isExpand);
/ fix node with sibling drag end */

$node.children('.leftEdge').toggleClass('fa-chevron-right', !isExpand).toggleClass('fa-chevron-left', isExpand);
$node.children('.rightEdge').toggleClass('fa-chevron-left', !isExpand).toggleClass('fa-chevron-right', isExpand);

}

function repaint(node) {
node.style.offsetWidth = node.offsetWidth;
}
});
if (opts.draggable) {
$nodeDiv.on('dragstart', function(event) {
event.originalEvent.dataTransfer.setData('text/html', 'hack for firefox');
var $dragged = $(this);
/* fix node with sibling drag begin /
if ($dragged.data('bContainsSiblings')) {
return false;
}
/ fix node with sibling drag end */

    var $draggedZone = $dragged.closest('table').find('.no
