This behavior is caused by a Google bug: when a map is at level 0 and "-" of 
zoom slider is clicked, a "zoom_changed" event is fired even though the map 
doesn't zoom out any further. In this situation, no "idle" event is triggered 
as usually happens when the map actually zooms.

MarkerClustererPlus removes all clusters in the zoom_changed handler, then 
redraws them when the subsequent idle event is handled. Since the latter never 
occurs when the map is at level 0, the clusters disappear.

This will be fixed in the next update to MarkerClustererPlus.

There is a fix for this in the current trunk release (2.0.9).

Using version 2.0.9, it appears that this is fixed at zoom level 0, but still a 
problem at max zoom.  E.g., if I don't have a maxZoom set, MarkerClusterer will 
create clusters when the map is zoomed all the way in, which is what I want.  
But if I zoom in, the cluster disappears.  The attached patch fixes the issue 
for me.

Sorry for the slow response - 2.0.10 fixes the issue for me.
