dshin-moz has just created a new issue for https://github.com/w3c/csswg-drafts: == [scroll-animations-1] `view-timeline` and keyframes that affect its own view progress == Since insets and sizes are animatable, it seems that one can pretty easily write something that modifies its own view progress. If it's defined in a way that decreases the coverage as the animation progresses, one can get the animation into a state where it's rapidly oscillating. Some test cases (**Strobing warning** - Small, but pretty annoying to look at.): * [With insets + relpos](https://github.com/user-attachments/files/25452319/vt.html) * [With height + static-pos](https://github.com/user-attachments/files/25452327/vt2.html) With both cases, I could get all 3 browsers into a strobing state by scrolling slowly around the point where the view-timeline animated element disappears off the top of the scroller.
