 * This will enable scroll locking for the provided element. Scroll locking works
 * by fixing the element within the page and hiding overflow for that element.
 * Since fixing an element in the page might cause scroll shifting or other behavior,
 * the element is also updated with a negative `top` style immediately so scrolling
 * and page shifting not happen. This offset value is determined by either the
 * current `pageYOffset` if the element is the `<body>` tag, otherwise it will be
 * the * `scrollTop` of the element.
 *
 * Finally, if the element is the `<body>` tag, the `left` and `right` styles will
 * also be updated to be `0px`. This is extremely helpful for most margin based
 * layouts (text pages). Without the `left` and `right` values being set to 0,
 * the entire page might shift unexpectedly again if the `<body>` was not updated
 * to have `width: 100%`.
 *
 * @param element Either the `<body>` tag or an element within the page to disable
 * scroll for.
