Bug Scene variables not working for state custom events

Not sure is it bug or no
Reproduce steps:

1. Create state graph (on gameObject marked as 'DontDestroyOnLoad')
2. Create scene variable (gameObject from scene in my case)
3. Create custom event (e.g. for "On Enter State" - it's working)
4. Try to get scene variable from custom event flow

Duplicate "VisualScripting SceneVariables" with zero variables will be created at runtime

I figured out scene variables not working for state machine component on gameObjects that was invoked
DontDestroyOnLoad

Main reason is scene param for Unity.VisualScripting.SceneSingleton that called under the hood is 'DontDestroyOnLoad' scene, not the actual active scene. This is why a duplicate VisualScripting SceneVariables object is created.
