This is referring to:

NS_IMETHODIMP ServiceWorkerShutdownBlocker::Notify(nsITimer*) {
  // TODO: this method being called indicates that there are ServiceWorkers
  // that did not complete shutdown before the timer expired - there should be
  // a telemetry ping or some other way of recording the state of when this
  // happens (e.g. what's returned by GetState()).
  UnblockShutdown();
  return NS_OK;
