Fix export 'useInsertionEffect' (imported as 'React') was not found in 'react' on React < 13

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @emotion/use-insertion-effect-with-fallbacks@1.0.1 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/@emotion/use-insertion-effect-with-fallbacks/dist/emotion-use-insertion-effect-with-fallbacks.browser.esm.js b/node_modules/@emotion/use-insertion-effect-with-fallbacks/dist/emotion-use-insertion-effect-with-fallbacks.browser.esm.js

   return create();

This issue body was partially generated by patch-package.

I'd love to see a repro case for the problem that you have experienced. It's important to know what exact tools were involved.

Thanks for your response! @Andarist

I have this error during webpack compilation.

ERROR in ./node_modules/@emotion/use-insertion-effect-with-fallbacks/dist/emotion-use-insertion-effect-with-fallbacks.browser.esm.js 5:25-52

Source code - /node_modules/@emotion/use-insertion-effect-with-fallbacks/dist/emotion-use-insertion-effect-with-fallbacks.browser.esm.js

import * as React from 'react';

var syncFallback = function syncFallback(create) {
  return create();
};

var useInsertionEffect = React['useInsertion' + 'Effect'] ? React['useInsertion' + 'Effect'] : false;
var useInsertionEffectAlwaysWithSyncFallback = useInsertionEffect || syncFallback;
var useInsertionEffectWithLayoutFallback = useInsertionEffect || React.useLayoutEffect;

export { useInsertionEffectAlwaysWithSyncFallback, useInsertionEffectWithLayoutFallback };

Recap: Code has fallback in declaration of var useInsertionEffect => webpack must not raise an error on import * step, Do you have any ideas?
Thanks! 😉

I need a full runnable/clonable repro case to debug this.
