Resolution Note (2022.1.X):
This is expected behavior. Old input uses information querying to retrieve active inputs. When the app is suspended (going to background, etc.) script execution is suspended as well, therefore the check to see that events were canceled does not happen. To handle lifecycle events use OnApplicationPause and OnApplicationFocus.
