Storage objects are created lazily when window.localStorage or window.sessionStorage is first accessed. Previously, broadcast() iterated over already-created Storage objects, so windows that had never accessed these properties would not receive storage events. Fix this by iterating over all active windows and initializing Storage objects as part of the broadcast loop so all eligible windows receive the event regardless of whether they had previously accessed their storage property.
