this.mapCtx.translateMarker 在subnvue中不支持吗

示例代码：

<map id="map" ref="map" v-if="longitude && latitude" :longitude="longitude" :latitude="latitude" scale="14" :markers="markers" :polyline="polyline"
show-location style="width: 750rpx; height: 1000rpx;"></map>

pageInit() {
console.log('324')

            console.log(this.mapCtx)  
            let that = this;  
            this.longitude = 114.085947  
            this.latitude = 22.547  
            this.mapCtx = uni.createMapContext('map', this);  

            // 坐标集合  
            let points = [{  
                longitude: this.longitude,  
                latitude: this.latitude  
            }, {  
                longitude: this.longitude + 0.01,  
                latitude: this.latitude + 0.01  
            }, {  
                longitude: this.longitude - 0.01,  
                latitude: this.latitude + 0.02  
            }, {  
                longitude: this.longitude - 0.01,  
                latitude: this.latitude + 0.01  
            }, {  
                longitude: this.longitude,  
                latitude: this.latitude

                width: 2  
            }]  
            console.log('dsds')  
            that.markers = markers  
            setTimeout(()=>{  
                that.translateMarker(markers);  
            },10000)  
        },  
        // 平移marker，带动画

            this.mapCtx.translateMarker({

操作步骤：

vue文件加subnvue就不支持

预期结果：

vue文件加subnvue就支持

实际结果：

vue文件加subnvue就支持
