We currently fail the following two WPT tests due to inconsistent values between what our ease-* or cubic-bezier functions produce, and what the WPT test is expecting:

  - web-animations/animation-model/keyframe-effects/effect-value-transformed-distance.html
  - web-animations/timing-model/time-transformations/transformed-progress.html (unproven, there are other failures in this test as well)

We need to determine how these tests work and why there is a difference between the results Chrome produces and what the test expects.

This may be related to issue 591607
