Thanks for the fast work Kent, but seems something is still off. I've updated to 5.5.0 and tests are still generating same act warnings. Am I missing something here? Do we need to actually use act inside the tests?

It's curious that I've actually removed a bunch of flushEffects calls which were necessary before and tests are passing just fine. Clearly act helped with that. And yet those warnings shouldn't be there. 🤔
