Javascript 高图表条下半部分消失

很多时候，我的highchart条形图的下半部分在向下钻取和向上钻取时消失。我甚至禁用了plotoptions上的动画，但这并不能解决我的问题，我无法在JSFIDLE上复制该问题，但不确定是否是由于高图表问题

Highcharts.chart('container', {
    chart : {
                    type : 'column',
                    events : {
                        drilldown : function(e) {
                            this.xAxis[0].setTitle({
                                text : 'Error Type'
                            });
                            this.setTitle({ text: "Error Distribution by Specifics" });
                             this.xAxis[0].update({
                                  tickInterval: 0,
                          });
                             
                        },
                        drillup : function(e) {
                            
                            
                            this.xAxis[0].setTitle({
                                text : 'Mean Absolute Error (in days)'
                            });
                            this.setTitle({ text: "Error Distribution by Days" });
                             this.xAxis[0].update({
                                  tickInterval: 0.5,
                          });
                        }
                    }
                }, 
    
    title: {
        text: 'Error Distribution (Days)'

                xAxis : {
                    title : {
                        text : 'Mean Absolute Error in Days'
                    },
                    type: 'category',
                    tickInterval : 0.50,

                yAxis : {
                    title : {

                plotOptions: {
                    column: {
                                animation:false
                    }

                tooltip : {
                    headerFormat : '',

                    pointFormat : 'Predicted Error Count : {point.y}'

    series: [

页面加载时的图像如下所示

现在，当我向下钻取，然后再向上钻取时，会出现下半部分

向下钻取过程中也会出现同样的问题。

通过在打印选项中添加clip:false解决了该问题，发现向下钻取时会生成额外的clipPath，删除它会根据您的描述解决该问题，这可能是一个highchart错误吗？你能在这里复制这个问题吗？不，我不能在jsfiddle上复制我在jsfiddle中复制了你的代码，但似乎一切都正常工作。
