https://archive.org/account/settings is one example where the shadow-dom seems to override anything set in dark-reader. I've yet to figure out how to override the shadow-dom outside of directly disabling the offending css within firefox's inspector. Even using the !important has no effect. archive.org seems to use css which both works with and without the var(--var-name, #fff) associated with shadow-dom, so I'm currently in the process of trying to find out if it's possible to just disable the shadow-dom entirely, whether it be per site, or everywhere. If it does turn out to be possible, it may make it a lot easier to fix sites like this so they don't end up with washed out text cause of only partially inverting the color-scheme. Might be cool if there's a toggle within dark-reader if it's possible to disable the shadow-dom per site as a debugging feature
