Whenever you open the VE, you will load the entire map box library. This seems highly undesirable for performance.

$1.mapbox

< {requiredBy: ["ext.kartographer.settings", "ext.kartographer.lib.topojson"], requires: []}

$1["ext.kartographer.settings"]

< {requiredBy: ["ext.kartographer.box"], requires: ["mapbox"]}

$1["ext.kartographer.box"]

< {requiredBy: ["ext.kartographer.visualEditor"], requires: Array}
