求助！为何我的自定义节点和边无法触发点击事件？只有画布canvas能响应点击事件？？

[Hugobuendiya]

这是我仿照文档写的一个自定义交互behavior，发现点击空白画布的时候可以触发打印：console.log('CanvasEvent',event)，console.log('CommonEvent',event)。
但是点击节点和边的时候，NodeEvent和EdgeEvent还有CommonEvent的点击都无法触发，这是为啥呢？？

registerBeTest(){
     class ClickAddNode extends BaseBehavior {

      constructor(context, options) {
        super(context,  options);
        this.bindEvents();
      }
       bindEvents() {
        const { graph } = this.context;
        graph.on(CanvasEvent.CLICK, this.addNode);
         graph.on(NodeEvent.CLICK, this.addNode1);
         graph.on(EdgeEvent.CLICK, this.addNode2);
         graph.on(CommonEvent.CLICK, this.addNode3);
      }
       addNode = (event) => {
        console.log('CanvasEvent',event)
      };
       addNode1 = (event) => {
         console.log('NodeEvent',event)
       };
       addNode2 = (event) => {
         console.log('EdgeEvent',event)
       };
       addNode3 = (event) => {
         console.log('CommonEvent',event)
       };
       unbindEvents() {
        const { graph } = this.context;
        graph.off(CanvasEvent.CLICK, this.addNode);
         graph.off(NodeEvent.CLICK, this.addNode1);
         graph.off(EdgeEvent.CLICK, this.addNode2);
         graph.off(CommonEvent.CLICK, this.addNode3);
      }
       destroy() {
        // 销毁时解绑事件
        this.unbindEvents();
        super.destroy();
      }
    }
    register(ExtensionCategory.BEHAVIOR, 'click-add-node', ClickAddNode);
  },
  
  behaviors：[
        {
          type: 'click-add-node',
        },
]

我搜索AI的解答说可能是pointerEvents的设置问题。我把节点和边都设置了pointerEvents:all后还是无法解决。点击节点和边时没有任何打印，包括CommonEvent.CLICK的打印也无法触发
