title: Issues with toggling layers with mapbox.js
body: <p>I am having issues with toggling map layers with mapbox.js. Using the code from [<a href="https://www.mapbox.com/mapbox.js/example/v1.0.0/layers/]" rel="nofollow">https://www.mapbox.com/mapbox.js/example/v1.0.0/layers/]</a> it pulls the basic mapbox base maps ex. mapbox.outdoors or mapbox.satellite as toggle layers, but the polygons on the personal map layer does not appear. I know that the map can be pulled by itself, but when I try to add it to a toggling map, the polygons do not appear. I am not sure if it is a problem with the code itself that isn't allowing my personal map to show, or if there is an issue with my mapbox map.</p>

  <p>Any ideas are welcome!</p>
