Code splitting: React.lazy() example is missing a Suspense wrapper

I'm not quite sure if this is intentional to only demonstrate how React.lazy() is used, if the API how lazy() works was changed after that part of the docs have been written already, if I am using it incorrectly or if it is actually wrong but in the example but in the code splitting guide you're using a component wrapped in a React.lazy() and do not wrap it in a <Suspense>:

https://reactjs.org/docs/code-splitting.html#reactlazy

When I do that I get an error message:

A React component suspended while rendering, but no fallback UI was specified.

Two paragraphs later Suspense is introduced and then a working example is shown where the lazy-loaded component is correctly wrapped in <Suspense> but I don't know if it is a good idea to have a non-functioning example in the documentation in the first place as it might be misleading.

閱讀連結 URL 上程式碼分割指南中的 React.lazy 部分，並將其中的範例與後面的 Suspense 範例進行比較。使用連結的 CodeSandbox 重現該行為，然後更新文件，使 lazy-loading 範例準確無誤，並且不會讓讀者誤解所需的 fallback UI。
