cesium 拾取错误开了贴地

cesium 开了 clampGround 会出现拾取失误，点击这个面高亮，别的面会高亮

上边还有个模型

解决办法

let editHandler = new SmartEarth.Cesium.ScreenSpaceEventHandler(Viewer.scene.canvas);
let previosObj = null;
editHandler.setInputAction(movement => {
  const pickedObjects = Viewer.scene.drillPick(movement.position);
  if (pickedObjects) {
    let pick = pickedObjects.pop();
    while (!pick.id && pickedObjects.length > 0) {
      pick = pickedObjects.pop();
    }
    if (previosObj) {
      previosObj.id.polygon.material = SmartEarth.Cesium.Color.fromAlpha(
        SmartEarth.Cesium.Color.BLUE,
        0.5
      );
    }
    if (pick.id && pick.id.polygon) {
      pick.id.polygon.material = new SmartEarth.Cesium.Color(1, 0, 0, 1);
      previosObj = pick;
    }
  }
}, SmartEarth.Cesium.ScreenSpaceEventType.LEFT_CLICK);
