Reported 2025-07-09 10:56:50 PDT

In Safari (including Safari 26 beta and Safari Technology Preview), box-shadow is not visually clipped when applied to an element with border-radius, even when the element has overflow: hidden. This causes shadows to appear rectangular rather than following the rounded shape of the element. Example on Official Tailwind Website: https://tailwindcss.com/plus/ui-blocks (see buttons)

Fixed on WebKit ToT (297198@main) (Minibrowser). @Simon - I think you might have already fixed it on ToT.
