Can't build a simple CRA app with v11.8.0

See original GitHub issue

Current behavior:

A build of a CRA app with React 17, MUI 5 (thus requiring emotion) fails quickly with:

Creating an optimized production build...
Failed to compile.
Attempted import error: 'useInsertionEffect' is not exported from 'react' (imported as 'useInsertionEffect$1').

This looks like the lib erroneously try to require something that’s only available in React 18, while my app uses React 17.

To reproduce:

I can build a CSB if you feel it’s better, but really the steps are:

Create a new CRA
Add MUI 5 and emotion
Setup MUI, Use a MUI component
npm run build

Expected behavior:

Build succeeds

Environment information:

react version: 17.0.2
@emotion/react version: 11.8.0

I’ve created a fix here and verified that it should work with CRA. I’m waiting for the CI and stuff but I should be able to release this somewhat soon.
