<!--

This is a simplified version of one case within the Blink web test
virtual/threaded-no-composited-antialiasing/animations/composited-animations-rotate-zero-degrees.html
but with will-change: transform added, so that it fails with the bug
that is introduced in the intermediate state of fixing
https://bugs.chromium.org/p/chromium/issues/detail?id=696374

<style>

@keyframes a {
  from { rotate: 0 1 0 44deg; }
  to { rotate: 0 1 0 44deg; }
}

div {
  width: 100px;
  height: 100px;
  animation: a linear 10s infinite;
  /* rotate: 0 1 0 44deg; */
  background: fuchsia;
  transform-origin: 100px 0;
  will-change: transform;
