An infinite loop in the cubic bezier function in src/timing-utilities.js was causing us to skip interfaces/KeyframeEffect/effect-easing.html from the web-platform-tests. This patch changes the loop condition to ensure it exits, in line with the CubicBezier implementation in Chromium. In order to achieve the accuracy required by the web-platform-tests expectations, the epsilon value in the algorithm is also reduced by an order of magnitude.
