Closing the GUI does not seem to terminate the flatpak process

[Mershl]

Description

Closing the GUI does not seem to terminate the flatpak process allowing for parallel processes and potential zombie processes of Boxes.

Reproducer

1) flatpak run org.gnome.Boxes 2) flatpak ps | grep .Boxes

Instance   PID   Application                          Runtime
2999822485  44717   org.gnome.Boxes org.gnome.Platform

3) Close the GUI using mouse or keyboard 4) flatpak ps | grep .Boxes

Instance   PID   Application                          Runtime
2999822485  44717   org.gnome.Boxes org.gnome.Platform

5) flatpak run org.gnome.Boxes 6) Do NOT close the GUI this time 7) Execute from a separate shell: flatpak ps | grep .Boxes

Instance   PID   Application                          Runtime
120344436  45630 org.gnome.Boxes                      org.gnome.Platform
2999822485 44717 org.gnome.Boxes                      org.gnome.Platform

Tested on

Gnome 41.1 (Fedora 35) flatpak 1.12.2

I thought Boxes wasn't launching but I realised it was this issue that's still happening. Reproduced the same way as with @Mershl. Was only able to solve it by running:

flatpak kill org.gnome.Boxes

Here's the logs from starting Boxes (after killing it) by running flatpak run -v org.gnome.Boxes and then closing it (after which it still runs and can't be re-open):

GNOME 43.4 (Fedora 37 Silverblue) Flatpak 1.14.4

Strangely after closing Boxes, flatpak run -v org.gnome.Boxes appears to still open it (previously this command wasn't). However, it still won't open from the GNOME app launcher.

Is this still reproducible ?

I cannot reproduce it on Debian unstable with flatpak-1.15.6. Maybe this is a Fedora specific issue ?

After clossing it from the GUI:

$ flatpak ps

If I kill the process with kill or flatpak kill then I can restart Boxes. Ubuntu 22.04
