Bug 503107

SUMMARY
I get extremely confused by the notification history if I have more than a few notifications in there. I guess it sorts it by app, grouping all notifications by the app sender and then sorts them from oldest to newest, which is 1. Extremely confusing, 2. Very inconvenient. It's confusing because from "Notification history" I would expect it to be chronologically sorted from newest to oldest. It's very inconvenient because if I missed something I can't just open the history and see what I missed, instead I have to scroll down and check last notifications of every app (or just scroll to the bottom if there's a lot of notification from one app)

STEPS TO REPRODUCE
1. Get a bunch of notifications from different apps at different times 
2. Open notification history using the tray icon or the widget

OBSERVED RESULT
Notifications are grouped by app sender and sorted top to bottom from oldest to newest

EXPECTED RESULT
Notifications are sorted from top to bottom, from newest to oldest, so by opening notification history one can see the last notifications they missed without hassle.
