application update causes dash icons to disappear as they would when closed
Original Bugreport: https://github.com/micheleg/dash-to-dock/issues/715
When someone for example on Arch Linux updates firefox while the application is running. Gnome no longer shows the application as open in the dash, and a click on the application icon creates a new window instead of opening the already open one.
Doing a shell reload fixes this issue.
Probably related: on my system, wireshark-gtk does not even show an icon in the dash unless I reload the shell.
