At the moment, this [block](https://github.com/plotly/plotly.js/blob/a72c6ee0e2ee7b509d9e7785f97c36768e411089/src/plot_api/plot_api.js#L1628-L1630) in `restyle` and this [one](https://github.com/plotly/plotly.js/blob/a72c6ee0e2ee7b509d9e7785f97c36768e411089/src/plot_api/plot_api.js#L2263) in `relayout` forces a full redraw whenever we update a geo subplot. We may need to expose a _translation_ projection attribute to secure the view from update to update.
