Issue description

I've been working on a solitaire game and my project has developed an issue. The scene card_body.tscn needs to have it's root node have the card_body.gd script attached to it. However, the project has developed some sort of an issue where this script keeps being removed form the editor.

Steps to reproduce

If I open the project, and open res://scene/card_body.tscn, the root node will have no script attached. I then click on the attach script button and attach card_body.gd. The project now works. However, if I save the project, exit and reload, card_body.tscn no longer has the script attached and I have to manually reattach it.

Do you have cyclic dependencies in the project?

[blackears]

None of my scripts are cyclicly dependent. Not sure if there is something more obscure that may be.

[heppocogne]

Not only preload(), typed GDScript can cause cyclic dependencies. for example:

class_name ClassA
var b:ClassB

class_name ClassB
var a:ClassA

And this may be related to #76641.
