STEPS TO REPRODUCE
1. Open a chat client and navigate to a chatty chatroom like the VDG room
2. Enter Do Not Disturb mode
3. Wait 15 minutes
4. Leave Do Not Disturb mode
A flood of on-screen notifications ensues, causing the right-hand side of the screen to be full of rapidly scrolling and disappearing notifications for the next minute.
Nothing happens; I don't need to see all of the notifications I missed. I missed them on purpose; that's why I entered Do Not Disturb mode.
I could *maybe* see the case for showing these notifications in the history popup (if they are marked as appearing in the history view), but putting them all on screen seems quite noisy and excessive to me.

libnotificationmanager: Expire all notifications when "Do not disturb" is on
After leaving "Do not disturb" mode, a flood of on-screen notifications
ensues, causing the right-hand side of the screen to be full of rapidly
scrolling and disappearing notifications for the next minute.
The user doesn't need to see any notification popup that is suppressed
by DnD mode, because the notification can be viewed from the drawer anyway.
