Re: [csswg-drafts] Remove the "content" requirement for ::before and ::after? [css-pseudo] (#3419)

The reason for this restriction is to avoid having to create `::before` and `::after` pseudo-elements for every element.  Removing it without a reasonable alternative would substantially increase the performance (at least one of speed and memory, and perhaps both) overhead of the feature.
