Theme breaks completely when using "color-scheme prefer-dark"

[Arcitec]

Hello, I am on the latest GIT code.

The theme becomes completely non-styled if "prefer-dark" is activated.

I am using Layan-Dark-Solid. But it seems to happen with all Layan themes.

# Break theme completely.
gsettings set org.gnome.desktop.interface color-scheme prefer-dark

# Fix theme.
gsettings set org.gnome.desktop.interface color-scheme default  

PS: I have copied the Layan-Dark-Solid/gtk-4.0 folder's contents to ~/.config/gtk-4.0/ and it does a decent job styling GTK-4/LibAdwaita applications. Great job! (This folder has nothing to do with the bug, I just wanted to thank you for having a semi-working GTK-4 already. :))

Forgot to say: This is a very important bug, because the "color-scheme" property is used by a TON of modern applications to determine some things:

• What color scheme to use for things like internal syntax highlighting (backgrounds, text colors). To avoid getting black text on dark theme background.
• It is used to hint what colors to use in totally non-GTK applications from other environments such as Qt.

While more a crude band aid fix than a real solution, I could work around the problem for now by setting the GTK_THEME=Layan-Dark environment variable explicitly globally.
Haven't noticed any major issues with this except some styling breaking in gnome-control-center (which I don't use much anyway) and obviously the light/dark-theme toggle breaking.

I've also experienced this issue and the workaround makes my desktop environment break (not a clue why, but it means it's not feasible to use; I'd have to add it to the app's desktop entry and that's not really accessible for most users).
