SAP Spartacus ComponentData的提前subscription

CmsComponentData：

包含一个uid和一个Observable：

CmsBannerComponent类型定义：

export interface CmsBannerComponent extends CmsComponent {
  headline?: string;
  content?: string;
  container?: string;
  media?: CmsBannerComponentMedia | CmsResponsiveBannerComponentMedia;
  urlLink?: string;
  external?: string;
}

这个ComponentData数据的一个例子：

{"uid":"SiteLogoComponent","uuid":"eyJpdGVtSWQiOiJTaXRlTG9nb0NvbXBvbmVudCIsImNhdGFsb2dJZCI6ImVsZWN0cm9uaWNzLXNwYUNvbnRlbnRDYXRhbG9nIiwiY2F0YWxvZ1ZlcnNpb24iOiJPbmxpbmUifQ==","typeCode":"SimpleBannerComponent","modifiedtime":"2020-09-28T22:43:51.668Z","name":"Site Logo Component","container":"false","external":"false","media":{"code":"/images/theme/SAP_scrn_R.png","mime":"image/png","altText":"SAP Commerce","url":"/medias/SAP-scrn-R.png?context=bWFzdGVyfGltYWdlc3wxMDEyN3xpbWFnZS9wbmd8aW1hZ2VzL2hmZi9oZWYvODc5NzUxOTM0Nzc0Mi5wbmd8ZmY3YjU2YzNmZjBkZDBjNjkwYzAyNDgyNWE0NjhhZjU2ZGFkNWFkODU3NjBhMDgxMzhmMmU5ZjFkMDhlNWEwNA"},"urlLink":"/"

重复subscribe没有问题：
