Description
我通过ref.current.getScrollInfo拿到的信息很奇怪
我的高度设置的是200，内容高度是动态(获取到的是700)，然后滚动到底部的时候scrollInfo.y显示的500，这个500的值应该是内容高度700-高度200.
但是我拿不到这个700的值，我就无法判断是否滚动到底部了
所以getScrollInfo能不能暴露更多的信息？

Research direction
Start by locating the implementation and public API for ref.current.getScrollInfo, then read how the virtual list calculates its viewport and content heights. Confirm which scroll information is currently exposed and define the smallest API change that lets callers determine whether scrolling has reached the bottom. Done means the additional information is available and its behavior is covered by an appropriate test.
