C# Export of custom typed array is un-assignable

[HarveyKBrown]

Godot version

4.0.1.rc2 & 4.0.0

System information

Win10, x64, TargetFramework .NET6.0

Issue description

When you export an array of a custom type in C#, you cannot assign values to the elements in the inspector.

Steps to reproduce

public partial class NodeType : Node2D
{
}

public partial class Icon : Sprite2D
{
	[Export]
	NodeType[] Nodes;

	[Export]
	NodeType SingleNode;
}

I have 2 Nodes, NODE_A (using script NodeType), NODE_B (using script Icon).

When assigning NODE_A to SingleNode, it works fine. When you assign a NODE_A to an element in the Nodes array, nothing happens, no value is assigned and the value remains as "Assign..." in the inspector.
