DialogOverlay
Apparently the previous fix was not enough as this can still be seen failing (https://github.com/ppy/osu/runs/5046718623?check_suite_focus=true). This change is copying from what other tests use seemingly reliably, such as `TestScenePerformFromScreen`)
As seen at https://github.com/ppy/osu/runs/4999391205?check_suite_focus=true, where `DialogOverlay` hasn't loaded in single file yet.
