Tái hiện cảnh báo với Python 3.13, ipympl 0.9.8 và một lệnh gọi plt.subplots sử dụng backend ipympl. Kiểm tra ipympl/backend_nbagg.py quanh Toolbar.__init__ và tương tác được nêu giữa traitlets với hàm khởi tạo của matplotlib; hoàn tất khi có thể tạo figure mà không gặp lỗi hoặc cảnh báo ngừng sử dụng đã nêu.
