The function UnloadSceneAsync does not work with variable data type SceneManagement.Scene

Reproduction steps:
1. Open the attached project;
2. Open the scene "Scene0";
3. Enter the Play mode;
4. Observe the Console window;

Actual result: an error "ArgumentExeception: Scene to unload is invalid" shows up. The load scene is not removed from the SceneManager.
Expected result: the load scene should be removed from the SceneManager.

Workaround: in the documentation is written that the function UnloadSceneAsync variable can be int, string and SceneManagement.Scene data types. Everything works correctly with int and string types. However, the function does not understand SceneManagement.Scene data type variable.

Reproduced with: 5.5.0b4, 5.5.0f3, 5.6.0b4
Not reproducible with 5.4 and older versions because the function "UnloadSceneAsync" is not supported.

    I can vouch for tiptip. This still is broken.

    this is not fixed.
    When using SceneManager.UnloadSceneAsync(sceneName)
    the scenemanger doesnt unload the scene.

    I have 5 scenes in BuildSettings,
    and when I run this piece of code on ios it throwing: "ArgumentException: Scene to unload is invalid"

    Debug.Log("sceneCount-> "+sceneCount);
    for (int i = 0; i < sceneCount; i++)
    Debug.Log("Scene Index-> "+SceneManager.GetSceneAt(i).buildIndex+ " name-> "+SceneManager.GetSceneAt(i).name);

    Reproduced with: 5.6, 5.6,1, 2017.1.0f1
