### 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
emit_signal(SNAME("object_id_selected"), p_id);
}
void EditorInspector::_resource_selected(const String &p_path, Ref<Resource> p_resource) {
	emit_signal(SNAME("resource_selected"), p_resource, p_path);
}
void EditorInspector::_node_removed(Node *p_node) {
	if (p_node == object) {
		edit(nullptr);
	}
}
void EditorInspector::_notification(int p_what) {
	switch (p_what) {
		case NOTIFICATION_READY: {
			EditorFeatureProfileManager::get_singleton()->connect("current_feature_profile_changed", callable_mp(this, &EditorInspector::_feature_profile_changed));
			set_process(is_visible_in_tree());
			_update_inspector_bg();
		} break;
		case NOTIFICATION_ENTER_TREE: {
			if (!sub_inspector) {
				get_tree()->connect("node_removed", callable_mp(this, &EditorInspector::_node_removed));
			}
		} break;
		case NOTIFICATION_PREDELETE: {
			edit(nullptr); 
		} break;
