Error when zooming out in scattergeo plot

[collioud]

Hello,

I have a scattergeo plot using the Aitoff projection. When positionning the mouse outside the projection area (but within the plot), then zooming out with the mousewheel, an error occur (see Firefox console stack below):

TypeError: point is undefined   plotly-latest.js:22222:7

Is this the expected behaviour (tell that you are zooming outside the projection scope)?

See this codepen for example:

BTW, is there a way to limit the zoom range in scattergeo plots? Maybe a zoom level available somewhere?

Thank you!
Cheers

Thanks for the report!
