Zoom does not respect Ctrl key for retaining aspect ratio

Riproduci il comportamento dello zoom del pulsante di panoramica nella configurazione JupyterLab segnalata, usando Firefox e il pulsante destro del mouse, e confronta il modificatore Ctrl con il modificatore x/y funzionante. Traccia la gestione degli input lato browser del widget del pulsante di panoramica; il lavoro è completato quando Ctrl mantiene le proporzioni durante lo zoom e il tooltip rimane accurato.

Describe the issue

The tooltip for the pan button widget includes the text "x/y fixes axes, CTRL fixes aspect". Holding down x/y works, but Ctrl does not retain the aspect ratio when zooming with the right mouse button (at least not in Firefox).
