Description
<List
data={[...new Array(100).fill(undefined).map((item, index) => ({ id: index }))]}
height={200}
itemHeight={30}
itemKey='id'
>
{(item) => <div>{item.id}</div>}
</List>
- 滚动条的位置刚好卡在高度的一半
- 如果height是动态值，我只要延迟设置height就正常，但这个时机不一定，可能是100毫秒，也可能是200毫秒以上。而且界面会弹一下
- 我这个组件是在弹窗里的

Research direction
Reproduce the reported List example with height 200 and itemHeight 30 inside a modal, then compare fixed and delayed dynamic heights. Start by tracing the virtual-list scroll-height and resize handling; done means the scrollbar reaches the expected position without timing-dependent delays or visible jumping.
