// Bug 1192692 - promiseBookmarksTree caches items without adding observers to
// invalidate the cache.

  // Note that for this test to be effective, it needs to use the "old" sync
  // bookmarks methods - using, eg, PlacesUtils.bookmarks.insert() doesn't
  // demonstrate the problem as it indirectly arranges for the observers to
  // be added.
