What I mentioned above is just a bug aspect, so I'd like to add more comment.
The web exposed serialization result will be the one resulted from css simplification. As an example of behavioral change of css calc simplification, it includes length canonicalization e.g. calc((12.5%*6 + 10in) / 4) is simplified to calc(18.75% + 240px), and the simplified result will be serialized. 2022년 3월 10일 (목) 오전 1:11, 박중헌 <[email protected]>님이 작성: > I think web exposed visible change will be calc serialized result, > e.g. calc(20% + 10px + 10em - 10%) will be serialized to calc(10% + 10em + > 10px) > while it is serialized to calc((20% + 10px + 10em) - 10%) with current > implementation. > > FYI, current change link is > https://chromium-review.googlesource.com/c/chromium/src/+/3489570 > which is a patch for reference, > and we are planning to proceed developing it behind a runtime flag > "CSSSimplificationAndSerialization". > > > > 2022년 3월 10일 (목) 오전 1:05, Yoav Weiss <[email protected]>님이 작성: > >> What are the web exposed implications of this?
