AssetsOnlyAttribute does nothing when with TableMatrixAttribute

What happened?

I decorated a public instance variable with the attribute AssetsOnlyAttribute. This instance variable was already decorated with the attribute TableMatrix. I assigned a scene GameObject to a cell in the matrix and there were no warning that it was not allowed.

How can we reproduce it?

using Sirenix.OdinInspector;
using UnityEngine;

public class MatrixTest : SerializedMonoBehaviour
{
    [Required]
    [AssetsOnly]
    [TableMatrix(SquareCells = true)]
    public GameObject[,] Assets = new GameObject[2, 2];
}
