### 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
if (use_editor) {
					
					
					sub_inspector->set_keying(false);
					_open_editor_pressed();
					if (is_inside_tree()) {
						get_tree()->call_deferred(SNAME("call_group"), "_editor_resource_properties", "_fold_other_editors", this);
					}
					opened_editor = true;
				}
				_update_property_bg();
			}
			if (res.ptr() != sub_inspector->get_edited_object()) {
				sub_inspector->edit(res.ptr());
			}
		} else {
			if (sub_inspector) {
				set_bottom_editor(nullptr);
				memdelete(sub_inspector_vbox);
				sub_inspector = nullptr;
				sub_inspector_vbox = nullptr;
				if (opened_editor) {
					EditorNode::get_singleton()->hide_top_editors();
					opened_editor = false;
				}
				_update_property_bg();
			}
		}
