### Godot version

v4.2.dev3.mono.official [013e8e3af]

### System information

Godot v4.2.dev3.mono - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3050 Ti Laptop GPU (NVIDIA; 31.0.15.3598) - AMD Ryzen 7 5800H with Radeon Graphics (16 Threads)

### Issue description

When creating and attaching a built-in script to any type of node, trying to drag nodes from the scene-tree results in an error that appears at the bottom-right of the editor, but not in the console window. The error states:

`Can't drop nodes because script 'xxxxxxxx::xxxxxxx' does not inherit Node.`
 Even though the script clearly extends Node or any other type.

### Steps to reproduce

1. Create and add any node type to the scene tree.
2. Attach a new script, choose Built-in from the dialog.
3. Save the scene first, as at the time of writing, Godot suffers from a bug that causes it to crash if the scene was not saved first.
4. Try dragging or even ctrl-dragging a node to the script.
5. Observe the error appear at the bottom-right in a yellow-accent pop-up.
6. Nod and confirm that the bug exists.
