[3.x] Exported variables not shown in inspector for autoloaded Scenes

[Maran23]

Godot version

3.x (3.5.1)

System information

Windows 10

Issue description

When starting Godot, exported variables are missing in autoloaded scenes.
They suddenly appear again when editing and saving the attached script, but only until a restart/reload.

I debugged already and found out, that this happens when another scene is preloaded in the autloaded scene.

Steps to reproduce

1. Open the project
2. Open the GlobalScene.tcsn
3. The exported variable is not visible
4. Go into the attached script -> change something -> save
5. The exported variable is visible
6. After a restart/reload, the exported variable disappeared again
