There are 8 tests failing the canonical serializarisation for opacity http://wpt.fyi/css/css-color/parsing/opacity-valid.html http://wpt.live/css/css-color/parsing/opacity-valid.html Copy Paste this in the URL bar of different browsers: data:text/html,<div class="test" style="opacity:clamp(50%,0%,70%)"></div><div class="log"></div><script>document.querySelector(".log").textContent=document.querySelector(".test").style.getPropertyValue("opacity");</script> which is <div class="test" style="opacity: clamp(50%,0%,70%)"></div> document.querySelector(".test").style.getPropertyValue("opacity"); It returns: 0.5 Safari Technology Preview 18.4 (220) 20622.1.14.5 cal(0.5) Firefox Nightly 141.0a1 14125.6.5 clamp(50%, 0%, 70%) Google Chrome Canary 139.0.7233.0 7233.0
