Description
css-backgrounds defines a box-shadow with border-radius spread algorithm (https://www.w3.org/TR/css-backgrounds-3/#shadow-shape) to achieve continuity or the radii of the outer edge when border-radius changes between zero to non-zero. The algorithm will be revised for https://github.com/w3c/csswg-drafts/issues/7103. The reason for applying the algorithm to box-shadow seems also apply to outlines, so should css-ui consider adopting the algorithm?

Research direction
Read the css-backgrounds shadow-shape algorithm and the linked CSSWG issue 7103 first, then compare their rationale with the outline behavior discussed for css-ui. Done would require a resolved CSSWG decision on whether outlines should adopt the algorithm and a corresponding specification direction.
