Bug 294363 – canonical serialization returns 0.5 instead of calc(0.5)

• Component: CSS
• Status: RESOLVED DUPLICATE

[Karl Dubost]

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
