I wonder if we could detect the case where Chrome doesn't work correctly, and only apply the polyfill then?

const timeoutID = setTimeout(() => {
  // We probably need to polyfill now.
}, 1000);

requestAnimationFrame(() => {
  clearTimeout(timeoutID);
});

That's a good idea! I'll submit a PR with that improvement tomorrow

const now = window.performance.now();
const nextTime = Math.max(lastTime + FRAME_TIME, now);
return setTimeout(function() {
callback((lastTime = nextTime));
}, nextTime - now);
};
window.cancelAnimationFrame = clearTimeout;
}

let panelCreated = false;
