在 TeXmacs/packages/standard/std-math.ts 中定义了 \det 的宏，但是实际使用时直接出现了文本 <img width="678" height="394" alt="Image" src="https://github.com/user-attachments/assets/882e3bd4-c836-476b-9818-399ee15b5b84" /> 回车会出现 <img width="228" height="106" alt="Image" src="https://github.com/user-attachments/assets/3459a518-1437-4f3f-9378-65f7510afe20" /> 正确行为是 <img width="252" height="144" alt="Image" src="https://github.com/user-attachments/assets/8d6d336e-4d7f-4869-aa4e-5214209c62ae" />
