As a side effect of LPS-73691, LPS-73695, LPS-73670 some changes have also been applied to requests that were only intended for notifications. Those changes are:

1. The new visual state for unread notifications.
2. The ability to filter by read/unread.
3. The ability to mark as read/unread a set of selected notifications.

This new features should only be present for notifications, not for requests.
