v5 - upsert 新增的元素没有 id，如何指定唯一 id 呢

[rtpacks]

wrapperHeader id 为空

class LinkNode extends Rect {
  drawWrapperShape(attributes: Required<RectStyleProps>, container: Group) {
   // wrapperHeader id 为空
    const wrapperHeader = this.upsert(
      "wrapper-header",
      Rect,
      {
        ...wrapperHeaderAttrs,
        transform: `translateY(${-wrapperHeight / 2 + headerHeight / 2})`,
        draggable: false,
        labelPlacement: "left",
        labelDx: headerWidth - headerPadding[1],
        // TODO replace tooltip
        labelText: "255.255.255.255",
        labelMaxWidth: wrapperHeaderAttrs.labelSize[0],
        labelWordWrap: true,
        labelTextOverflow: "ellipsis",
      },
      container,
    );
    console.log(`${wrapperHeader?.id}`);

    return this.upsert("key", Rect, attributes, container);
  }
}
