When I receive an e-mail in Thunderbird or a chat message in Dino and Slack, the Gnome Shell shows a notification.
I open/switch to the application (without clicking on the notification), read the message - and the notification stays there in the shell. I have to manually remove the notification.
This is with Gnome Shell 48.7 on Debian 13.
Is this the way it has to be, or should notifications get removed automatically when I view the message in the application that sent the notification?
