Custom Javascript (Post) – still in problem with v2.7.34

Hello, I post a message 10 months ago about a problem with the settings and Custom Javascript (Post). https://ww.wp.xz.cn/support/topic/custom-javascript-post-code-change-since-2-7-29/

With version 2.7.34 it’s ok when I save it in the settings but the result is the same. You can see in the developer console that the function is not correct.

post: function( $ ){
		// Custom JavaScript (Post)
		$('.fbx-instance').on('foobox.beforeShow', e) {
	var $element = $(e.fb.item.element),		//the anchor tag
		$fooboxInstance = e.fb.instance,		//the foobox instance
		$modal = e.fb.instance.modal.element;	//the modal object

	//your custom code goes here...
