Till now we never enabled window.requestAnimationFrame(rAF) API, recent WebKit upgrade(JDK-8183292) enables rAF by default. Most of the websites which uses rAF calls the API through polyfill interface[1]. So it was working earlier, after JDK-8183292 only the API exists without any implementation.

Partial rendering is due to missing requestAnimationFrame[1]. Previous WebKit disabled by default[2], but recent upgrade enables rAF by default[3]. From platform side we should provide an implementation or enable the default implementation available in WebKit.
