We're calling userEvent.type and userEvent.click inside of act which triggers the warning since these functions call act themselves.

This occasionally fails because queryByText('Add Client') returns null and the expect fails. I'm not sure why it fails to find the button (I don't see any logic that would delay the button being rendered), but using findByText allows the test to wait for it to appear.

I spent the most time troubleshooting this test and found that it fails by timing out nearly every time when running alongside the rest of the test suite.

(The quickest way to reproduce I've found is to run yarn test src/features/PlacementGroups src/features/Profile, but this may vary from machine-to-machine).

What I've found is that the test, interactions, etc. all work exactly as expected, but when running alongside other tests some of the interactions (specifically and surprisingly the userEvent.click(submit)) take a really long time to execute. I don't think it has anything to do with the component itself.

My (purely speculative) guess is that when transpiling/running a lot of tests concurrently, the CPU is taking such a hit that it's slowing down JSDom to the point that the tests are timing out. I opened a ticket to reassess Happy DOM which might prove or disprove this theory, but in the meantime increasing the timeout seems to be a reliable (if unfortunate) mitigation.
