Created attachment 466698 [details] a simplified usecase where clip-path inset radius does not render When using clip-path: inset() with border-radius values, the radius is not rendered on specific cases of element size, radius size and clip-path size. In the attached code example you can see an element 661px wide and 445px high with "clip-path: inset(11.2923% round 50% 50% 0% 0%)." The radius of these exact dimensions fails consistently (At least on MacOS 13.2.1 Safari 16.3, Safari Tech Preview 171, and iOS 16.5). Any change to the width, height, clip-path size or border-radius will "fix" the issue. Also attached a link to an animated codepen where different element sizes and different radius values "glitch" on different points on the timeline
