当为 tab 设置 flex 响应式布局时,在特定宽度下,tabs 会和 dropdown 抢占位置导致抖动现象。
原因在于采用 dom.offsetXXX 来计算 tab 的宽度是不准确的。 dom.offsetXXX 为四舍五入取整值,在响应式布局下会丢失精度,导致在计算的时候产生误差,最大误差为 0.5 * n。

具体错误代码:
src/hooks/useVisibleRange.ts 46

if (offset[position] + offset[unit] > transformSize + mergedBasicSize)

实际上很多利用 offsetXXX 的计算都会存在误差。
