branch: 7.8
user: Cédric Krier <[email protected]>
date: Fri Mar 20 18:41:23 2026 +0100
description:
Limit the size of the notification payload send to the bus
The payload size is limited by the database but also there is no point
to
overflow the user with too much notification popup.
So we publish only the first 4 messages and shorten them to 100 chars
per line.
Closes #14698
