 * Back-compat effect for routes that previously requested the app sidebar's

 * but {@link SidebarContext} keeps the global navigation expanded. Cleanup
 * still clears the request when the route unmounts.
 *
 * Drop it anywhere inside a route's element tree:
 *
 * ```tsx
 * function MyPluginPage() {
 *   return (
 *     <>
 *       <RequestCollapsedSidebar />
 *       …
 *     </>
 *   );
