/**
 * Renders a draggable handle and drop-target line that let users reorder
 * top-level blocks by dragging. You supply the handle and target-line elements
 * via `menuComponent`/`menuRef` and `targetLineComponent`/`targetLineRef`, an
 * `anchorElem` to portal them into (defaults to `document.body`), and an
 * `isOnMenu` predicate used to detect interactions with the handle.
 *
 * @experimental The API may change in a future release.
 * @returns A portal containing the drag handle and target line.
