uni.createSelectorQuery().in(this).select(sel).boundingClientRect(data => {}) data 数据异常

安卓系统app，获取#id 的节点布局位置 异常，有哪位知道怎么回事，怎么修改
代码如下：

                let prePos = 0;  
                query  
                    .select(sel)  
                    .boundingClientRect(data => {  
                        console.log("get scroll data " + data.top +" " + data.bottom +" " + data.height+ " " + sel);  
                        if(data.bottom != prePos){  
                            uni.pageScrollTo({  
                                scrollTop: data && data.bottom,  
                                duration  
                            });  
                            prePos = data.bottom  
                        }else{}  
                    })  
                    .exec();

在滚屏十几行后，异常出现了，读取的位置data反复跳回之前的固定位置数据，导致滚屏出现跳跃的情况
