Summary Nested @supports queries do not inherit parent declarations

As of Safari Technology Preview 175 (Safari 17.0, WebKit 18617.1.1.2), nested @supports rules are not applied consistent with implementations in Blink and Gecko. In the Codepen linked below, the border color declaration is overridden by the color value specified in the @supports rules and the border-radius rule in the parent selector is completely ignored. https://codepen.io/Membranophonist/pen/rNQPYXe
