/**
 * Same as React's lazy(), except that if the fallback is rendered in the
 * Suspense, this guarantees that it will be rendered for a minimum duration (1
 * second by default). This is useful when showing temporary content spinners,
 * progress indicators, skeletons, etc. Although it seems counterintuitive to
 * delay showing the real content longer than necessary, showing these temporary
 * placeholders for too short a duration causes a quick "flash" of content
 * change that can be disorienting. Showing them for a minimum duration allows
 * the user to understand what is happening.
 *
 * @param factory Produces a promise of the real component to show.
 * @param minDuration = The minimum amount of time (in milliseconds) that must
 *   elapse before the promise will resolve. This will NOT be applied when
 *   invoking preload().
