4 years ago i think the main issue is not css many of the javascript libraries and custom code are hardcoded left and right you can see my fork (i am just playing there) https://github.com/rhayun/jellyfin-web-rtl
i used gulp-rtlcss to auto RTL all the css (some need fixes manually) and then i notice many issues with video player and scrolls i fixed some - but for sure not the best way to do that
Now that we have translations in some RTL languages, we should investigate what is needed to support RTL layout for those languages.
