[Bug] "Close to tray" setting is always forgotten after suspend or reboot

[7system7]

Your setup

• SONE version: v0.20.0
• Install source: Flatpak
• Distro + version: Arch (rolling)
• Desktop / session: GNOME 50.3 on Wayland
• GPU + driver: Advanced Micro Devices [AMD/ATI] Navi 23 [Radeon RX 6600/6600
  XT/6600M] (Mesa 1:26.1.3-2)

What went wrong?

"Close to tray" setting is always resetted (to false) after the system reboot or after suspend.

Additional (and I think, it is an important) information: I do not use GNOME w/ "system tray" extensions and as we know that, the GNOME does not support the classic system tray. Meanwhile the SONE perfectly works in the background and GNOME shows it in the "Background apps" section. Only the setting is not saved by the app.

What did you expect to happen?

I enable "Close to tray" and it just works after I reboot the system.

How can we reproduce it?

1. Install SONE from flatpak. (I used Bazaar for installing)
2. Start it and set up close system tray.
3. It does not save this setting after reboot.

Screenshots or recordings

I meant this setting

SONE in the GNOME's "background apps"
