css-borders-4 extends some of the property declarations of css-backgrounds-3 (
border-xxx-radius
,border-xxx-color
). This creates duplicate CSS property definitions in Webref.If we were to consider css-borders-4 as a delta spec, we would just do nothing and leave de-duplication up to consumers. Here, we need to select one. If we favor css-backgrounds-3 definitions, e.g., on the ground that they are more stable, we would have to reverse that choice later on when that stops being the case. Favoring css-borders-4 definitions seems more future-proof. Plus the new definitions are backward-compatible with former ones.
