Description
Has anyone ever tested a component with Jest that was using this library? I'm having issues with some old unit tests failing due to IntersectionObserver not being defined. I'm having trouble mocking IntersectionObserver and was wondering if anyone else has run into this.

Research direction
Start by reproducing the old unit-test failure in the Jest setup and confirm that IntersectionObserver is the missing global. Check how this library's components are rendered in the tests, then verify that the tests run successfully with the required IntersectionObserver mock in place.
