Serializable class array defaults

Hi,
So I’m trying to get default values to work when creating an array of serializable class.

The serializable class looks like this:

[System.Serializable]
public class WaveDefinition
{
     public float WaveLength = 5.0f;
}

and the other class where I create the array looks like this:

public class PopulateArray : MonoBehaviour
{
  
    [SerializeField]
    private WaveDefinition[] _Waves;
}

in this case the default value for the first element is always 0.
If I modify this value and add another element the default value of the new element will be the same as the previous element.

I tried using ISerializationCallbackReceiver to initialize the values like so:

    [System.Serializable]
    public class WaveDefinition : ISerializationCallbackReceiver
    {
        public float WaveLength = 5.0f;
        private bool _Deserialized = false;

        public void OnBeforeSerialize()
        {
        }

        public void OnAfterDeserialize()
        {
            if (_Deserialized)
            {
                return;
            }

            this.WaveLength = 5.0f;
            this._Deserialized = true;
        }

    }

while this works to set the default values, when I add an other element all of the elements will be reset to the default values.

Can someone help me figure this out?
Thanks!

Yeah, I know this is a long time bug, but I hoped someone found a workaround after all those years.

The solution with ISerializationCallbackReceiver almost works, just need to find a way to avoid the reset of all elements to the defaults values when adding a new one.
