Moving it as you suggested works fine locally, but in testing on CI the test fails on all OS's due to `buttonMouseEnteredCount` being non-0. I'm assuming since the listener is added earlier in the test, the count would be 1 instead since the Robot's mouse movement would enter the button area once, but then the test fails locally. I'll keep the addition of the button listener where it originally was to avoid having the complexity of solving this both locally and in CI.

Sure. This may be slightly odd to see a count reset mid-test instead of retaining the original position of adding the listener, but I think this is fine. I re-tested on CI to make sure this still passes, and it looks good on all OS's. Thanks for the suggestion.
