[csswg-drafts] [css-borders-4] Specify how `corner-shape` affects `outline` (#12194)

noamr has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-borders-4] Specify how `corner-shape` affects `outline` ==
Follow up to https://github.com/w3c/csswg-drafts/issues/11610#issuecomment-2876877811.
Outlines are "special" because they create a path that's external to the original border, more like a stroke.
A concave corner (e.g. a star of `scoop` shape) with a big outline might end up with very long miters.

Note that currently `outline` rendering is specified in pretty vague terms.

Proposing (based on suggestion from @smfr) to advise implementations to render a round miter for concave corner-shaped outlines.
