源码地址：

问题代码块：
const scroll = (frame = 0) => {
const dest = from delta * easeFunc(frame)
scrollFunc(dest) <---------------------此处是问题代码
if (frame < frameCnt) {
timer && clearTimeout(timer)
timer = setTimeout(() => {
scroll(frame 1)
}, FRAME_DURATION)
} else {
return handle.success({}, { resolve, reject })
}
}

问题：
设置top时，变量 frame 的正确取值范围是 0 - （frameCnt -1）
在最后一次循环调用时rame === frameCnt，easeFunc(frame)的值会大于1，导致dest的值比期望值多了一帧的量

解决方案： scrollFunc(dest)的执行，应该移动到 if (frame < frameCnt) 条件内部

期望结果

滚动准确

实际结果

滚动偏差，多滚动了一帧
