This is a simple emotion 11 app replicating the create-react-app starting template. Use this if you need a simple app to test the browser extension issue found at craigsketchley/emotion-11-extension.

It's important the app is run in production mode to reproduce the clashing with the emotion 11 browser extension.

To run the app (in production mode):

npm i && npm start

If you install the browser extension then you should encounter the issue where the extension strips a lot of the styles from the in-page app.
