ThreeJs CSS3DObject 点击失效问题

想实现一个在选中物体，弹出菜单，结果发现，点击会失效

	  <ul id="menu" class="list-group list-group-full"><li class="list-group-item" onclick="test()">24小时曲线</li><li class="list-group-item" onclick="test()">72小时曲线</li></ul>

	  const tag = new CSS3DObject(dom);tag.scale.set(0.05, 0.05, 0.05); //缩放标签尺寸let position = this.getWorldPosition(this.hightLightObject);let size = this.getSize(this.hightLightObject);let offsetY = size.y / 2;tag.position.x = position.x + offset.x;tag.position.y = position.y + offsetY + offsetY / 4 + offset.y;tag.position.z = position.z + offset.z;this.scene.add(tag);

之前绑定在dom中click事件不会触发。

Google了一下，找到解决方法

dom.addEventListener('pointerdown', () => { alert(2) })
