Is it possible to activate legacy minifiers for CSS only?
The problem is that the new minifiers don't work for CSS (script error 500) and if I solve that problem with define("AUTOPTIMIZE_LEGACY_MINIFIERS","true"); Google says the my HTML could be optimized by 5%.
The new minifiers reach 100% optimization for HTML.
So the best of both worlds would be new minifiers for HTML and legacy minifiers for CSS.
