### Tested versions

### System information

### Issue description

I'm testing the "skeleton" example in godot 4.3 beta 3 extract from here:


This is what appears when you open the character's scene.


I assume this is a bug or problem with the display of the bones because the documentation does not show it like this:


I'm talking about the look of the bones, they look too big, I'm not talking about the problems that show a yellow notice.

### Steps to reproduce

...

### Minimal reproduction project (MRP)

...

No source file or test is named. Start by opening the skeleton example scene in Godot 4.3 beta 3 and varying the editor camera zoom to reproduce the oversized Skeleton2D gizmos; done means the gizmos render independently of editor zoom and match the expected appearance.
