   * and throw an error if it's not able to access this.view.map or etc
   * (happens in VersionManagementViewModel for example).
   *
   * We can't check for this in disconnectedCallback though as, if the entire
   * component tree is removed, the disconnect for the component will be
   * triggered before that of arcgis-map, so the view might not be destroyed
   * yet at that point.
