Visual Studio Code, though preconfigured by default with a dark theme, has a light titlebar, suggesting that Electron detects a light theme in the system.

Some Electron-based applications are unable to detect that the system is running with a dark theme, despite dark mode being the default configuration for openSUSE Aeon. This can lead to a lack of UI consistency.

I noticed this primarily in apps like Visual Studio Code and Signal. It's worth pointing out that this doesn't occur on every Electron app (namely, the Webcord Flatpak is able to handle theming just fine). I'll also point out that this isn't necessarily an issue with the apps alone or GNOME, because the aforementioned apps--whether packaged as a Flatpak, tarball, or run within a distrobox--do correctly use a dark theme on Ubuntu 23.10.

I'm not an expert on SELinux, but it is my best guess as to why this is happening.
