Javascript confirmjs弹出式背景动画在firefox中不起作用

我正在开发Jquery确认js弹出窗口。背景动画在firefox最新版本中不起作用。我调试了jquery-confirm.js插件文件，发现在单击背景空间时没有触发click事件。代码存在于“jquery confirm.js”插件中，我只是添加了我发现问题的引用。有人能帮我吗？

插件中的默认代码：

$(document).on('click','.jconfirm-open',function(e){ 
         if(!that.boxClicked){`
                var buttonName = false;
                var shouldClose = false;
                var str;

                if(typeof that.backgroundDismiss === 'function')
                    str = that.backgroundDismiss();
                else
                    str = that.backgroundDismiss;

                if(typeof str === 'string' && typeof that.buttons[str] !== 'undefined'){
                    buttonName = str;
                    shouldClose = false;
                }else if(typeof str === 'undefined' || !!(str) === true){
                    shouldClose = true;
                }else{
                    shouldClose = false;
                }

                if(buttonName){
                    var btnResponse = that.buttons[buttonName].action.apply(that);
                    shouldClose = (typeof btnResponse === 'undefined') || !!(btnResponse);
                }

                if(shouldClose)
                    that.close();
                else
                    that.hiLightModal();
            }
            that.boxClicked = false;
        });

this.$scrollPane=this.$el.find（'.jconfirm scrollPane'）

最新修改代码：

$(document).on('click','.jconfirm-open',function(e){ 
         if(!that.boxClicked){`
                var buttonName = false;
                var shouldClose = false;
                var str;

                if(typeof that.backgroundDismiss === 'function')
                    str = that.backgroundDismiss();
                else
                    str = that.backgroundDismiss;

                if(typeof str === 'string' && typeof that.buttons[str] !== 'undefined'){
                    buttonName = str;
                    shouldClose = false;
                }else if(typeof str === 'undefined' || !!(str) === true){
                    shouldClose = true;
                }else{
                    shouldClose = false;
                }

                if(buttonName){
                    var btnResponse = that.buttons[buttonName].action.apply(that);
                    shouldClose = (typeof btnResponse === 'undefined') || !!(btnResponse);
                }

                if(shouldClose)
                    that.close();
                else
                    that.hiLightModal();
            }
            that.boxClicked = false;
        });

上述类“.jquery scrollPane”单击事件在firefox浏览器中不起作用，尤其是在最新版本中。我尝试过使用父div类（检查弹出窗口，你会发现）并应用click事件，它在所有浏览器中都有效
