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.

リンク先のURLにあるコード分割ガイドのReact.lazyセクションを読み、その例を後のSuspenseの例と比較してください。リンク先のCodeSandboxを使って動作を再現し、その後、lazy-loadingの例が正確になり、必要なfallback UIについて読者に誤解を与えないようにドキュメントを更新してください。
