Keeps reseting appearance to light mode theme every background-panel load

[Augustin Berisa]

Steps

1. Have dark mode enabled
2. Open settings at background panel
3. Shell theme is reset back to light theme

It keeps resetting theme back to light one every time you open the panel which is unwanted.

Could you paste the output of this command?

dconf dump /org/gnome/desktop/interface/

Before unwanted reset:

```
$ dconf dump /org/gnome/desktop/interface/
[/]
clock-show-seconds=true
clock-show-weekday=true
color-scheme='prefer-dark'
cursor-theme='Yaru'
enable-animations=true
enable-hot-corners=true
font-hinting='slight'
gtk-enable-primary-paste=false
gtk-theme='Yaru-red-dark'
icon-theme='Yaru-red-dark'
text-scaling-factor=1.0
```

After opening Appearance panel which keeps showing Dark settings as set yet it gets reset:

```
$ dconf dump /org/gnome/desktop/interface/
[/]
clock-show-seconds=true
clock-show-weekday=true
color-scheme='prefer-dark'
cursor-theme='Yaru'
enable-animations=true
enable-hot-corners=true
font-hinting='slight'
gtk-enable-primary-paste=false
gtk-theme='Yaru-red'
icon-theme='Yaru-red'
text-scaling-factor=1.0
```

Here's a workaround that may help. Close your settings app then run these commands in your terminal

gsettings reset org.gnome.desktop.interface gtk-theme
gsettings reset org.gnome.desktop.interface icon-theme

Then open the Settings app and set your preferred theme.

@jbicha That doesn't affect the misbehavior.

Another steps to reproduce

1. Set light theme in Appearance panel
2. Close Settings gnome-control-center
3. Enable dark mode in gnome-shell's aggregated menu
4. Open Appearance panel
5. GTK3 legacy and gnome-shell theme is always reset to light at this point.
6. Dark mode switch in aggregated menu is reset to light
7. Only GTK4 apps remained dark as expected since no action was taken by user.

$ dconf dump /org/gnome/desktop/interface/
[/]
clock-show-seconds=true
clock-show-weekday=true
color-scheme='prefer-dark'
cursor-theme='Yaru'
enable-animations=true
enable-hot-corners=true
font-hinting='slight'
gtk-enable-primary-paste=false
gtk-theme='Yaru-magenta'
icon-theme='Yaru-magenta'
text-scaling-factor=1.0
toolbar-detachable=true

There is being made mismatch somewhere between gtk3, gtk4 and gnome-shell theme.

No extensions enabled.
