I'm getting an error after upgrading to React 18. Don't really understand what this means tbh and wasn't getting it before!

And I don't use IntersectionObserver in my codebase

The tests failing have a 3rd party component that uses IntersectionObserver

ReferenceError: IntersectionObserver is not defined

  7 |   expect(baseElement).toBeTruthy();

sure its react fault ?, does your codebase uses `IntersectionObserver` ? – bogdanoff May 10 '22 at 14:33
