Subject: extend ApplyWebPreferences with Electron-specific logic
background_color can be updated at runtime, as such we need to apply the
new background color to the WebView in the ApplyPreferences method.
There is no current way to attach an observer to these prefs so patching
is our only option.
Ideally we could add an embedder observer pattern here but that can be
done in future work.
