Quick Look feature doesn't seem to work. At least background color is not changed, and dark mode not enabled when opening white SVGs.
I first tried manually copying the SVG.qlgenerator into the /Library/QuickLook folder and run "qlmanage -r" as well as restarting Finder, without results. Then restarted the Mac, still no results.
