### Godot version

4.0 beta 10

### System information

Windows 10, Vulkan

### Issue description

While the fishbone pattern is visible, the points are not. (Invisible) points can be added to a path and deleted from it, but they can't be moved in the editor viewport, only via inspector properties.
I haven't used 4.9b, but I confirmed the point handles are visible in 4.8b on my system (same file).

### Steps to reproduce

Make a Path3d. Add points via Inspector. Fail to see point handles in the viewport.

### Minimal reproduction project

n/a
Node *to_node = get_node(p_path);
	if (!Object::cast_to<Viewport>(to_node)) {
		EditorNode::get_singleton()->show_warning(TTR("Selected node is not a Viewport!"));
		return;
	}
	Ref<ViewportTexture> vt;
	vt.instantiate();
	vt->set_viewport_path_in_scene(get_tree()->get_edited_scene_root()->get_path_to(to_node));
	vt->setup_local_to_scene();
	emit_changed(get_edited_property(), vt);
	update_property();
}
void EditorPropertyResource::setup(Object *p_object, const String &p_path, const String &p_base_type) {
	if (resource_picker) {
		memdelete(resource_picker);
		resource_picker = nullptr;
