When you drag a sortable item over another sortable item's drag handle and right click, the sortable item you were dragging is dropped but not in the placeholder (correct location). At this point the placeholder is still at the original location of the dragged item and the dragged item is dropped where you right-clicked.

$(document).ready(function(){
	$("#zone_0").sortable({
	  items: 'div.wf_widget',
		handle: 'div.wf_widget_header',
		revert: false,
		scroll: true,
		placeholder: 'wf_widget_dropcue',
		connectWith: $('div.wf_zone'),
		opacity: 0.7,
		stop: function() { stopSort(); },
		dropOnEmpty: true,
		helper: function() { return $("#helper").clone().show(); },
		zIndex: 10000
	});

	$("#zone_1").sortable({
	  items: 'div.wf_widget',
		handle: 'div.wf_widget_header',
		revert: false,
		scroll: true,
		placeholder: 'wf_widget_dropcue',
		connectWith: $('div.wf_zone'),
		opacity: 0.7,
		stop: function() { stopSort(); },
		dropOnEmpty: true,
		helper: function() { return $("#helper").clone().show(); },
		zIndex: 10000
	});
});
