ReorderableList and ShowAssetPreview do not work together

[orangy]

Add this code to ReorderableListTest and try to drop a prefab into the list.

		[ReorderableList]
		[ShowAssetPreview]
		public List<GameObject> prefabList;

It doesn't work and throws NRE.

I know. Unity's CustomPropertyDrawers target each element of arrays. ReorderableList however is implemented with a custom solution and it targets the arrays themselves. This is the reason why it's not working. A workaround is to have something like this:

[ReorderableList]
public List<PrefabWrapper> prefabList;

[Serializable]
public struct PrefabWrapper
{
    [ShowAssetPreview]
    public GameObject prefab;
}

I know it's not pretty, but this is the best solution I can think of.
I'll fix the exception, and log an error, but I won't be able to fix the behavior.

The 2 attributes can actually be combined. The problem is that it works only with the default width and height of the [ShowAssetPreview] attribute
