[Bug]: Resetting Suspense boundaries on navigation not work

Summary

Resetting Suspense boundaries on navigation not work

Details

I come up with an example as the documentation says:

However, now imagine you’re navigating between two different user profiles. In that case, it makes sense to show the fallback. For example, one user’s timeline is different content from another user’s timeline. By specifying a key, you ensure that React treats different users’ profiles as different components, and resets the Suspense boundaries during navigation. Suspense-integrated routers should do this automatically.

However, key do not work as expect, i.e. I did not see a loading indicator

从 Suspense 参考页面开始，并在 src/App.js 中运行其中链接的 CodeSandbox 复现。将观察到的导航行为与页面关于 key 会重置 Suspense 边界的表述进行比较，然后确定需要修正的是示例还是文档。复现出所报告的差异，并且页面或示例准确反映该行为，即视为完成。
