Bug description

When the number of notifications is large, I cannot scroll through the list of notifications. As a result, notifications are not accessible.

See the screenshot below:

(there are a lot more notifications, but as the list length grows indefinitely, the scrollbar is never shown)

Steps to reproduce

Create a lot of notifications. This can be done with a command like the following (creates a dummy hello notifications 20 times):

for i in {1..20}; do notify-send "Hello" "Notification $i"; done

Do not close the notification when it appears. Instead, let them close on their own (after a few seconds), and let them accumulate in the notification tray.

Expected behavior

The scrollbar in the notifications list should be activated.

Additional information

I initially reported a similar error in #13760, and then was able to pinpoint the specific error by discussing with developers.

This is fixed by setting a maximum height to the notifications list. I will send a PR soon.
