Xianzhu Wang dc7fcb3291 Bug 1702616 [wpt PR 28342] - Try to deflake css/css-animations/nested-scale-animations.html, a=testonly
Automatic update from web-platform-tests
Try to deflake css/css-animations/nested-scale-animations.html

- Reduce the size and the scale to avoid maximum scale clamping (which
  is the mainn reason of the test failing under virtual/threaded on
  Chrome).
- Use 'forwards' instead of 'infinite' for the animation, so that in
  case of capture happening after the end of the animation, the test
  will still pass.
- Wait for start of the animation, to avoid the test ending before the
  animation starts.
- Increase the delay of capturing to be near the end of the animation,
  to avoid the capture happening during animation from scale 1 to 10.
