ipympl crashes when panning/zooming

Personne n'a encore pris cette issue.

## 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:

```

## Versions
I suppose I'm using the latest versions of everything (under Python 3.10.9), sinceI just installed everything from scratch on a new Mac M1 (which has the developer tools and rosetta).

Reproduisez le crash dans un notebook en affichant un graphique et en faisant glisser avec le contrôle de zoom ou de panoramique, en utilisant la configuration signalée avec Python 3.10.9 et ipympl 0.9.3. Commencez par l’assertion de Tornado et les versions des paquets Jupyter indiquées ; c’est terminé lorsque le panoramique et le zoom peuvent continuer sans que le serveur ou la connexion ne plante.
