```javascript
/**
 * Keeps WordPress core's admin-menu pinning in sync with the real page height.
 *
 * Core measures #wpwrap once and reuses that figure to decide whether to pin
 * the admin menu. Plugin pages change height after that measurement — tab
 * panels being shown or hidden, list tables loading over AJAX, sections
 * expanding — and core is never told. It then works from a stale height,
 * concludes the page is too short to pin, and lets the menu scroll off-screen
 * on a page that is in fact tall enough.
 *
 * Watching the document for height changes and re-firing the event core
 * already listens for keeps the two in agreement, without having to patch
 * every feature that changes layout.
