/**
 * A local implementation of the async clipboard interface.
 *
 * This implementation just stores the clipboard data in memory, but not in the clipboard.
 * This implementation can be used if you don't need to support cross-widget/browser/application
 * data transfer and you would like to avoid to require the permission of the user for accessing the
 * system clipboard asynchronously.
 *
 * In order to detect whether the user copied something else since we recorded the clipboard data
 * we put a uuid into the system clipboard synchronously. If on paste this ID has changed or is not
 * available anymore, we know that the user copied in another application or context, so we shouldn't
 * paste what we have stored locally and just return undefined.
 *
 * Real async clipboard service implementations can just ignore the ID that is passed and rely on the
 * system clipboard's content instead.
