Apparently, so far the best solution is to draw twice the markers with different sizes.
Check last example of https://plot.ly/python/scattermapbox/

However, this means twice as much points, and then slower plots.
You can configure the upper marker to have hoverinfo, the lower marker without hoverinfo, and so on.

Hope it helps
