ipympl crashes when panning/zooming

Tái hiện crash trong một notebook bằng cách hiển thị một biểu đồ và kéo bằng điều khiển thu phóng hoặc xoay, sử dụng thiết lập Python 3.10.9 và ipympl 0.9.3 được báo cáo. Bắt đầu với assertion của Tornado và các phiên bản gói Jupyter được liệt kê; hoàn tất khi có thể tiếp tục xoay và thu phóng mà không làm server hoặc kết nối bị crash.

Describe the issue

After a plot gets displayed in a notebook, I select either the zoom or pan button, move the cursor over the plot, and drag it to execute the operation. The plot correctly responds for a little while, but soon the server crashes with this error:
