高德地图3D模式下PathSimplifier轨迹显示错误

高德地图3D模式下调用PathSimplifier，会使网页显示的地图强制变为俯视视角，设置的角度失效，网页上也无法调整，导致网页上显示的轨迹偏移，通过地图缩放可以看出。求大佬帮忙看看问题出在哪儿了，感激不尽！！！

路径数据导入的外部文件。地图JS代码如下

    var buildings = new AMap.Buildings({
        'zooms':[3,20],
        'zIndex':10,
        'heightFactor':2//2倍于默认高度，3D下有效
    });//楼块图层 
    //创建地图
    var map = new AMap.Map('container', {
       viewMode:'3D',
        pitch:60,
        rotation:-35,
        features:['bg','road','point'],//隐藏默认楼块
        mapStyle:'amap://styles/light',
        layers: [new AMap.TileLayer.Satellite(),//高德默认标准图层
                 buildings],
        center: [116.360159,39.961302],
        resizeEnable: true,
        expandZoomRange:true,
        zoom:15,
        zooms:[3,20]
    });

    AMapUI.load(['ui/misc/PathSimplifier', 'lib/$'], function(PathSimplifier, $) {
        if (!PathSimplifier.supportCanvas) {
            alert('当前环境不支持 Canvas！');
            return;
        }

        var pathSimplifierIns = new PathSimplifier({
            zIndex: 100,
            autoSetFitView: false,
            map: map, //所属的地图实例

            getPath: function(pathData, pathIndex) {

                return pathData.path;
            },
            getHoverTitle: function(pathData, pathIndex, pointIndex) {

                if (pointIndex >= 0) {
                    //point 
                    return pathData.name + '，点：' + pointIndex + '/' + pathData.path.length;
                }

                return pathData.name + '，点数量' + pathData.path.length;
            },
            renderOptions: {

                renderAllPointsIfNumberBelow: 100 //绘制路线节点，如不需要可设置为-1
            }
        });

        window.pathSimplifierIns = pathSimplifierIns;

            endIdx = 0,
           myData = [{
                      name:'无人机路径',
                      path: data.slice(0, 1)
                      }];
        pathSimplifierIns.setData(myData);

        //对第一条线路（即索引 0）创建一个巡航器
        var navg1 = pathSimplifierIns.createPathNavigator(0, {
            loop: true, //循环播放
            speed: 50 //巡航速度，单位千米/小时
        });

        function expandPath() {

            function doExpand() {

                endIdx++;

                if (endIdx >= data.length) {
                    return false;
                }

                var cursor = navg1.getCursor().clone(), //保存巡航器的位置
                    status = navg1.getNaviStatus();


                myData[0].path = data.slice(0, endIdx + 1);
                pathSimplifierIns.setData(myData); //延展路径


                //重新建立一个巡航器
                navg1 = pathSimplifierIns.createPathNavigator(0, {
                    loop: true, //循环播放
                    speed: 50 //巡航速度，单位千米/小时
                });

                if (status !== 'stop') {
                    navg1.start();
                }

                //恢复巡航器的位置
                if (cursor.idx >= 0) {
                    navg1.moveToPoint(cursor.idx, cursor.tail);
                }

                return true;
            }

            if (doExpand()) {

                setTimeout(expandPath, 3000);
            }
        }


        navg1.start();

        expandPath();

    });

这个组件好像在3D效果下有问题
