Markers are invisible by default.

Prompted by this StackOverflow question. If you simply add a marker to the map, following the example in the API docs:

var marker = new mapboxgl.Marker()
  .setLngLat([30.5, 50.5])
  .addTo(map);

You don't actually get a visible marker. A <div> element is created, with class .mapboxgl-marker, but there is no styling associated with it, so it's completely invisible.

Example: https://codepen.io/stevebennett/pen/RpKVjy

(remove the '-REMOVETHIS' to make the marker visible...)

If this is intended behaviour, it seems really confusing, newbie-unfriendly, and ought to be better documented.

I agree! We're tracking this in #3557.

Is this still the case? I can't figure out how this codepen example works: https://codepen.io/allthesignals/pen/NWvvqmV

Running mapbox-gl 2.5.1, I can't get this default appearance to work.
