I have Source Prefab class with some ValueObserver called "value" and Watcher Prefab class with LinkedObserver called "_state"

Then, in Unity Editor I set _state linked observer to watch SourcePrefab.value

In WatcherPrefab I do:

    private void Start() {
      _state.AddListener(onStateChange);
    }

It doesn't work as Unity somehow does not call LinkedObserver's constructor, caches _isObserverInitialized as "true" (I checked with debugger) and _state.Observer remains null, despite it being set in the editor.

I use Unity 6
