EditorSceneManager.sceneClosing callback not called when loading a single scene

Scene Management

-

I register a callback for the EditorSceneManager.sceneClosing event but it doesn't get called when I open another scene in the editor.

Steps to reproduce:
1. Open the attached project: SceneClosingNotCalled.zip
2. Open alternatively SceneOne and SceneTwo.
3. Observe the Console.

Expected: SomeBehaviourEditor.OnSceneClosing() gets called and a message about it gets printed in the console.
Actual result: No message is printed in the console about closing the scene and the function SomeBehaviourEditor.OnSceneClosing() is not called.

Note: If the two scenes are loaded additively and then one of them gets Unloaded or Removed then the closing callback gets executed as I would expect.

Tested in Unity 2017.2.0a2

    Same on 2018.3.2.
    I am currently using this workaround:

    UnityEditor.SceneManagement.EditorSceneManager.sceneOpening += OnSceneOpening;

    private void OnSceneOpening(string path, OpenSceneMode mode)
    {
    if (EditorSceneManager.sceneCount < 2 && mode == OpenSceneMode.Single)
    {
    // A scene is being opened in single mode. Which means another one is being closed.
    }
    }

    This only covers the case where sceneClosing event doesn't work. Therefore, you should still register to sceneClosing event for scenes that are being closed/unloaded in additive mode.

    I've got this problem too.

    I guess I'll let it be, assuming it will be fixed. An AssetStore product throws an error on scene change and only way to avoid it is if this callback method works.

    Same problem here, 2017.2.0f3. Also, same behaviour when a scene is opened with EditorSceneManager.OpenScene(buildScene.path, UnityEditor.SceneManagement.OpenSceneMode.Single).
