Bug (?)

**What is the current behavior?**

Currently, the 16.3.x versions of `react-dom` ship [`react-dom.development.js`](https://unpkg.com/react-dom@16.3.1/cjs/react-dom.development.js) containing usage of `Array.from` which is not available in certain React-supported browsers like IE11. It causes breakage if those particular code paths are taken in such a browser (I ran into it using `<StrictMode>` in IE11).

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below:**

Reproduction (should see "Hello, world!" but IE11 will crash and show nothing):
https://codepen.io/anon/pen/zWJBrO?editors=0010

**What is the expected behavior?**

`react-dom.development.js` would not use `Array.from` or document that a polyfill is required.

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

`react` and `react-dom`: 16.3.0-alpha.0 through 16.3.1
Internet Explorer 11
