The part in the spec that deals with [four-directional shorthand properties](https://drafts.csswg.org/css-logical/#logical-shorthand-keyword) leaves out `border-radius` I've seen the [CSSWG resolution about logical border-raduis](https://lists.w3.org/Archives/Public/www-style/2015Feb/0504.html), but as far as I understand it only covers longhead properties. I think `border-radius` should be included in the shorthand spec, same way as its longhand values. **Edited**: to add missing link to CSSWG resolution
