Two years later, I've run into the same issue. The MarkerManager seems to
ignore markers if the current viewport is below the minimum configured for
the MarkerManager. Certainly seems counter-intuitive to me. Whether or not
a marker is displayed at a given level shouldn't prevent you from managing
add/removal of the marker, regardless of zoom level.
Anyone know how to workaround this issue?
