AtlasTexture under CanvasTexture's diffuse renders solid white

### Tested versions

4.2.1 and 4.2.2 both stable official

### System information

Godot v4.2.1.stable - Windows 10.0.22631 - Vulkan (Mobile) - dedicated NVIDIA GeForce RTX 3060 (NVIDIA; 32.0.15.5585) - 13th Gen Intel(R) Core(TM) i7-13700KF (24 Threads)

### Issue description

Adding a CanvasTexture to Sprite2D, then adding an AtlasTexture and defining area to the Diffuse option of the CanvasTexture. First the sprite in the editor looks empty and when i move it it becomes pure white instead showing the texture I defined. No matter the image file type.
Re opening the scene sometimes fixes it.


### Steps to reproduce

Create a Sprite2D > add a CanvasTexture Resource > open diffuse option of the Canvas Texture > add an AtlasTextrure > put a texture in it and define an area using the AtlasTexture editor > move the transparent sprite in the editor
