react-testing-library cleanup doesn't work in codesandbox

Question

cleanup doesn't work in codesandbox and I comment the ReactDOM.render function as someone suggesting to in here: https://github.com/CompuIves/codesandbox-client/issues/1525 and it works, but fireEvent doesn't work. Vice versa, when I don't comment the ReactDOM.render function, fireEvent works and cleanup doesn't.

RTL doesn't work well in codesandbox. Run your tests in your local machine instead.
