ember-test-waiters Tests hang

Here is a demo that hangs consistently in Firefox in headless mode, or being run via ember test --server

https://github.com/amk221/-ember-waiters-issue/commit/4f41d022212a8f3949ce5510ed3a0e2a68f29d0a#diff-539124910b2d9910320f2b3c5516639c1a1e417847d0ae2769c1f839e13b713dR20-R31

I am secretly hoping its not an issue specific to Firefox, but just shows up in it easier. And that if fixed would iron out flakes I see in our test suite of > 8000, where occasionally we'll see pending test waiters cause the tests to eventually bomb out even in Chrome

Did you end up finding out why the click wasn't working at all?

(We dobegged this sowe in discord, and the promise is never resolved due to a click not working, which is why the test hangs (this click is expected to resolve the promise))
