Your intuition is correct - there's nothing to indicate any delay. Look at your profiler. Notice any significant overhead? You don't. Implement this same thing using events and `.style` directly. You will get the exact same result. The pointerEvent => style feedback loop is unfortunately very slow, more or less so in different browsers/operating systems.
