/**
 * Forces an element to stay a fixed, full-viewport overlay despite host CSS.
 *
 * Applies the fixed/inset/size rules with `!important` and re-applies them via a
 * MutationObserver whenever the host rewrites the element's `style`, so a widget
 * overlay cannot be shrunk or repositioned by the surrounding app. Only active
 * while `active` is true.
 * @param {RefObject<HTMLElement | null>} elementRef - The overlay element ref.
 * @param {boolean} active - Whether to enforce the overlay.
 * @param {ForceFullScreenOverlayOptions} [options] - pointer-events / z-index overrides.
 * @returns {void} Nothing.
