What is the current behavior?

When react-dom is loaded from CDN like <script src="https://cdn.jsdelivr.net/npm/react-dom@16.12.0/umd/react-dom.development.js"></script>, react-refresh failed to inject hook into devtools.

I've created a related issue here: pmmmwh/react-refresh-webpack-plugin#13

We should find a way to invoke injectIntoGlobalHook function from react-refresh/runtime, however this file is in cjs format so we cannot currently do this in a simple way.

What is the expected behavior?

I'd like react-refresh to publish runtime as a umd bundle so we can reference it from CDN and put it before react-dom's <script> element, then invoke injectIntoGlobalHook in the right place.

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

• react-dom: 16.12.0
• react-refresh: 0.7.0
