Bug

**What is the current behavior?**

React 16.10.0 has broken all Next.js applications (and potentially other SSR solutions).

It appears you cannot `hydrate` in conjunction with a client-side `<Suspense>` component.

> Expected to have a hydrated suspense instance. This error is likely caused by a bug in React. Please file an issue.

**CodeSandbox**: https://codesandbox.io/s/i66g1

**What is the expected behavior?**

Not entirely sure -- I'm opening this issue to discuss. The provided example worked in React 16.9.0 (and prior releases containing Suspense).

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

`react@16.10.0`/`react-dom@16.10.0` is broken.
`react@16.9.0`/`react-dom@16.9.0` works.
