Removing individual markers from map at the end of animation

[ghost]

I'm having a hard time removing each individual marker from the map as soon as they stop. Tried using methods isEnded() and end without much sucess. With (end), the following code removes only but one marker (I am guessing that it is removing the first to stop). Full code here:

marker.on('end', function() {
  map.removeLayer(this);
  });

With a click event instead of an end event, each marker is made easily removable, but then this is not what I am looking for:

marker.on('click', function() {
  map.removeLayer(this);
  });

What am I missing here?
