Description Simon Fraser (smfr) 2020-02-20 22:28:45 PST

The examples on https://css-tricks.com/animating-the-content-property/ don't work properly; we don't go between A and B, and you don't see the countdown before BOOM

It is now working in Safari 16.2 and Safari Technology Preview 161. Although we have artifacts where edges of A and B remain and we transition between and similar when we go below 3, it has smear artefacts.

Should we track these issue within this or have separate for these cases? Thanks!

No, that's OK, I think we can keep this bug. We must fail to compute the repaint area correctly here.
