Code

public function unregister() {

  // Normally, there are definitely wrappers set for the ALL filter. However,
  // in some cases involving many container rebuilds (e.g. WebTestBase),
  // $this->wrappers may be empty although wrappers are still registered
  // globally. Thus an isset() check is needed before iterating.
