- force the time dilation to 1.0 for the Widget tests, so that a local change doesn't break all the tests during development. - add missing license block to all the files. - set ui.window.onBeginFrame to null when you use WidgetTester, so that the engine doesn't trigger any confusing frames after our fake frames.
