Bug: React UMD cannot run in strict mode

React version: 16.2.0

Steps To Reproduce

Run the code in your console:

import(‘https://cdn.jsdelivr.net/npm/react@16.12.0/umd/react.development.js’)

The current behavior

Uncaught (in promise) TypeError: Cannot set property 'React' of undefined

The expected behavior

React get loaded in the browser as globalThis.React.

Suggestion

Head of https://cdn.jsdelivr.net/npm/react@16.12.0/umd/react.development.js

'use strict';

(function (global, factory) {
	typeof exports === 'object' && typeof module !== 'undefined' ? module.exports = factory() :
	typeof define === 'function' && define.amd ? define(factory) :
	(global.React = factory());
}(this, (function () { 'use strict';

The this in the last line will always be undefined in strict mode. Consider use this || globalThis

Yeah we’d be happy to bump Rollup if there’s a fix.

It’s working in React 16.13.0
