Issue description

MeshInstance3D objects will not render when changing SecondNode3D scale. Code when hidden

mesh_instance.scale = Vector3(0.6, 0.6, 0)

But when I use the following code, it will render

mesh_instance.scale = Vector3(0.6, 0.6, 0.6)

I'm not sure if this is correct

Steps to reproduce

extends Node3D

@onready var mesh_instance = $Camera3D/Node3D

func _ready() -> void:
    change_size()

func change_size():
    mesh_instance.scale = Vector3(0.6, 0.6, 0)

Scene tree structure:

It's child of the camera node so it's probably out of view somehow.

You set one of the components of scale to 0, of course it won't render

It should still render though. I present to you a torus of scale.y = 0

Yes, when I create a mesh object in the scene and modify the scale value in the editor interface instead of using a script, the object will be rendered.
