Exported nodes aren't available / set in [Tool] scripts

Godot version

v4.0.2.stable.mono.official [7a0977c]

System information

Ubuntu 22.10

Issue description

Exported nodes don't seem to be set before a script marked as [Tool] is run in the editor.

Steps to reproduce

Either use the attached project or do the following:

1. Create a new scene, and attach a new C# script to the root node

using Godot;
using System;

[Tool]
public partial class main : Node3D
{
    [Export]
    public Node3D NodeTest;

    // Called every frame. 'delta' is the elapsed time since the previous frame.
    public override void _Process(double delta)
    {
        GD.Print(NodeTest.Name);
    }
}

2. Build the solution, and associate any node to that exported variable.

Even though it's set, the node isn't accessible from within the editor.

• Related to Exported typed variables in a tool script have wrong initial value if not initialized #62363 and Exporting Node variable can't trigger setget in tool mode. #69283.

Can you reproduce this in GDScript?

[timshannon]

Confirmed, yes, it happens with GDScript as well:

• This seems like it was fixed by Fix typed array export #76389. The PR is included in Godot 4.1.
• Can you still reproduce this issue in Godot 4.1 or any later release?

[timshannon]

@raulsntos confirmed working great now in 4.1.

Thanks,
