* Don't call idle callback unless there's time remaining * Expiration fixture Fixture that demonstrates how async work expires after a certain interval. The fixture clogs the main thread with animation work, so it only works if the `timeout` option is provided to `requestIdleCallback`. * Pass timeout option to requestIdleCallback Forces `requestIdleCallback` to fire if too much time has elapsed, even if the main thread is busy. Required to make expiration times work properly. Otherwise, async work can expire, but React never has a chance to flush it because the browser never calls into React.
