How can I disable automatic forced dark mode on websites?

I have selected 'Dark/Auto' in my customization settings. I assumed this setting was meant strictly for the Firefox app UI theme, not to automatically force dark mode onto web pages. However, the issue now is that websites are being forcibly rendered in dark mode. I actually appreciate forced dark mode because it renders images and colored text cleanly without messing them up. The real problem is that I can't seem to find any option to turn it off. When I try enabling dark mode using a website's own native toggle, it displays inverted/negative colors, whereas light mode works properly. So my question and issue come down to this: how do I disable the feature that automatically forces dark mode on the websites I browse? (I haven't been able to find this setting anywhere.)
