Choropleth map zoom not functioning in safari

I have deployed my app and I’m happy with the rendering on most browsers. However, the zoom functionality is not working on Safari (but fine on Chrome and Firefox).

I have a go.Scattermap object and the zoom is fine on all three browsers. The go.Choropleth map is where I have the issue.

Is anyone aware of this problem and is there a known work around?
