If your event listener is connected to a marker, *but that marker is otherwise free to be garbage collected*, then the event listener will not prevent your marker from being garbage collected. Of course, you must take the usual care to ensure that your marker is free to be garbage-collected. It cannot be referenced from any other JavaScript Object, Array, or Function (closure).
