I tried it out (build the new react modules and stuck them in an existing project's node_modules/cypress) and it's working great, nice job :100:

Nice, second latest job went all green: https://app.circleci.com/pipelines/github/cypress-io/cypress?branch=zachw%2Ffix-react18-unmount

Not sure why the info in the checkbox is showing red, maybe because I canceled the later build (due to the previous one passing). Let's ship it.
