Re: [csswg-drafts] [css-conditional-3] [css-fonts-4] Allow CSS.supports('font-family: system-ui') for feature detection

I don't think using `'font-family: system-ui'` works here, because 
simply wrapping it with parens `'(font-family: system-ui)'` makes it 
pass on all browser. We may need a function syntax for this kind of 
thing.
