Bắt đầu với bản tái hiện StackBlitz được liên kết và theo dõi component Select trong khi cuộn trang với menu đang mở. So sánh chiều cao của menu khi nó rời khỏi và quay lại viewport; hoàn tất có nghĩa là chiều cao lại mở rộng sau khi cuộn trở lại để menu hiển thị, như được mô tả trong hành vi mong đợi.
