### Godot version

v4.0.1.stable.official [cacf49999]

### System information

Windows 10

### Issue description

If you use Sprite2D with a regular CompressedTexture and set a Region on it, then use a Sprite2D with a CanvasTexture and a different texture in the diffuse, and try to set a Region, the Region Editor display will show the texture from the first sprite2D node. I would expect it to show the diffuse texture from the current Sprite2D.

### Steps to reproduce

Make a sprite2D node
add a texture to it 
set Region to Enabled
click Edit Region under 'Region'
set any region

Make another sprite2D node
add a CanvasTexture to it
add a different texture to the Diffuse part
set Region to Enabled
click Edit Region under 'Region'
see wrong texture
