How can I utilize the dark theme in Opera without having web pages display in dark mode? I've tried setting the #enable-force-dark flag to 'Disable' (which worked in the past), but it is no longer reverting websites to light mode.
More specifically, I think I am looking for a flag (or setting) in Opera to tell webpages that the browser is running with the light theme, regardless of which theme is actually chosen. Does this exist? If not, can it exist?
