The labels are not captured properly. There are supposed to be labels for the 10 largest cities, but no labels are present.

I'm not sure it will ever make sense to support conversion of this class of extension (including #2019) because the results change with the size of the R graphics device, and so we'd have to essentially re-implement these extensions client-side for them to work correctly on resize, which would be a very big project.

Ideally, plotly/plotly.js#4674 would get implemented in a way that would support these extensions, but that also seems difficult/unlikely
