On 21.04 after the sleep exceeds the 3s timeout a new info message box
is displayed.
On 21.10 after the sleep exceeds the 3s timeout nothing is shown.

Title:
Notify method not working correctly in 21.10 (impish)
Status in dbus package in Ubuntu:
New
Bug description:
The replaces_id parameter to org.freedesktop.Notifications.Notify no longer
works correctly at 21.10.
It is OK on 21.04.
At 21.10 if a message with replaces_id === x ever times out then any
further message sent with that replaces_id never gets shown. The
timeout-over seems to become permanent for that replaces_id.
Example program to follow....
