4.5.beta1 Error when initializing resources via inspector

[TemporalCatcher]

Tested versions

Reproducible in: 4.5.beta1
Not reproducible in: 4.5.dev5

System information

Windows 11 - Godot 4.5.beta1

Issue description

When I initialize a new resource variable in the inspector after previously initializing the variable on the same load, Godot spits out this error:
ERROR: Another resource is loaded from path '::' (possible cyclic resource inclusion).

the '::' would be an address and file of the current scene/resource. So if I had a saved scene at res://sprite_2d.tscn and produced the error in the file it will produce the error:
ERROR: Another resource is loaded from path 'res://sprite_2d.tscn::' (possible cyclic resource inclusion).

Steps to reproduce

1. Open any project, or even create a new one
2. Create a new Sprite2D scene
3. In the inspector > Texture, Select CanvasTexture (or any texture) - No Error
4. In the inspector > Texture, Select CanvasTexture again (or any other texture) - Error
5. Save the scene and Reload
6. Do Step 3 and 4. It should yield same result as 3 and 4 respectively.

Sprite2D is just an example, any node/resource that has a resource variable that you can initialize should produce the error.
It must be under New, if you load a resource, it will not spit out the error.

This only happens when you create 2 resources in a row without saving the scene. I think the only proper solution is making the path generate with an ID. Right now it's deferred until the scene is saved.
