[3.x] Can't assign Resource's exported variable of type Script in Editor

[Celthim]

Tested versions

Godot 3.6 and 3.6.1

System information

Windows 11

Issue description

I use export Script variables in my Resources to be able to drag&drop effects for my cards in my game. It's not the first time I'm using this technique and have done it before in Godot 4 also. Until recently I was on Godot 3.5 and updated my project to Godot 3.6.
Since then, I can't drag&drop my scripts inside my Resources' variables. I tried on 3.6.1 and it doesn't work either.

Steps to reproduce

• Create a Resource
• Add a export(Script) variable
• Create any Script
• Try to drag&drop the script above in the Script variable of the Resource

Minimal reproduction project (MRP)

Duplicate of #104126 ?

Myself I'm unfortunately totally unfamiliar with this area and I can't work out what I should be doing or what I should be looking for, so maybe a video showing the process and what goes wrong and what goes right could help.

The objective would be to bisect down to a commit which may have caused this change, so knowing whether it works in any of the 3.6 betas would be useful, and which one it broke in.

UPDATE:
Ah I've been able to reproduce it in the other issue MRP (it's a bit simpler).

We can close this if it is confirmed as a duplicate.
