+/**
+ * Wrapper for ResizeObserver, with fallback for browsers that don't support ResizeObserver.
+ *
+ * Calls the onResize callback once layout is complete, and again whenever any of the target(s) change size.
+ * Or if ResizeObserver isn't supported, calls the callback whenever the window changes size.
+ *
+ * @param target - Either a single element, or array of elements to watch for size changes.
+ * @param onResize - Callback to be notified when layout is complete, and when the target(s) change size.
+ *    If this browser supports ResizeObserver, the callback will be passed the ResizeObserverEntry[] array.
+ *    Otherwise, the entries array will be undefined, and you'll need to find another way to get the element's size,
+ *    (e.g. clientWidth/clientHeight or getBoundingClientRect).
+ *
+ * @returns A function to clean up the observer/listener.
