-AsyncOperation is returned from native timing. For example, await `SceneManager.LoadSceneAsync` is returned from `EarlyUpdate.UpdatePreloading` and after called, loaded scene called from `EarlyUpdate.ScriptRunDelayedStartupFrame`.

+AsyncOperation is returned from native timing. For example, await `SceneManager.LoadSceneAsync` is returned from `EarlyUpdate.UpdatePreloading` and after called, loaded scene's `Start` called from `EarlyUpdate.ScriptRunDelayedStartupFrame`. Also `await UnityWebRequest` is returned from `EarlyUpdate.ExecuteMainThreadJobs`.
 
 In UniTask, await directly and `WithCancellation` use native timing, `ToUniTask` use specified timing. This is usually not a particular problem, but with `LoadSceneAsync`, causes different order of Start and continuation after await. so recommend not to use `LoadSceneAsync.ToUniTask`.

 A pull-type asynchronous stream does not get the next values until the asynchronous processing in the sequence is complete. This could spill data from push-type events such as buttons.
