Description Martin Robinson 2022-02-15 06:09:38 PST
perspective(0) is always rounded to perspective(1px), so should not be considered a transform operation. This is causing several WPT tests in the CSS Transforms suite to fail.

Looks like you missed a WPT progression in imported/w3c/web-platform-tests/web-animations/animation-model/animation-types/interpolation-per-property-002.html :)
