ipympl crashes when panning/zooming

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:

[E 16:08:31.532 NotebookApp] Uncaught exception, closing connection.

Riproduci il crash in un notebook visualizzando un grafico e trascinando con il controllo dello zoom o della panoramica, utilizzando la configurazione indicata con Python 3.10.9 e ipympl 0.9.3. Inizia con l’asserzione di Tornado e le versioni dei pacchetti Jupyter elencate; il lavoro è terminato quando la panoramica e lo zoom possono continuare senza che il server o la connessione vadano in crash.
