- we don't close them when receiving a push message without event_id
as we always need to have a notification open after a push message
and replacing them with a generic one like we did is worse than just
leaving it open
- after the second notification for a room, we just show "New messages"
and you don't get binged again for new messages after that.
- You will still have a notification for every room, and on Android
you will just see the one for the last room as it only shows one
notification at a time.
- also here don't use client.url to figure out if a session is open
as that doesn't work in FF
- use tag to make sure we're dealing with the right type of notif
- use findClient function
- use event.waitUntil to prevent default notification
- replace notifications for same room
- replace notifications when receiving unread=0 with "Read messages"
to prevent default notification
- don't rely on client.url to figure out if a room is open as FF
does not update this field on hash changes.
