/**
 * Efficiently detect when an HTMLElement is resized.
 *
 * Attaches an invisible "resize-sensor" div to the element. Then it checks
 * the element's offsetWidth and offsetHeight whenever a scroll event is
 * triggered on the "resize-sensor" children. These events are further
 * debounced using requestAnimationFrame.
