By just commenting out !isDragging you introduce a usability issue whereby dragging the map while the mouse is over a cluster icon will zoom in once you finish the drag, just like if you've clicked it.

Here is a simpler fix I've implemented which fixes the issue in Chrome and allows dragging to behave as expected. Remove the existing mousedown and mousemove events on this.div_ and replace with this:

google.maps.event.addDomListener(this.div_, 'mousedown', function () { google.maps.event.addListenerOnce(that.map_, "dragstart", function () { isDragging = true; }); isDragging = false; });

For IONIC users' sake I am adding my fixes.

In mobile there is no 'mousedown' or 'mousemove' event defined so I use 'dragstart', 'dragend' envent instead.

google.maps.event.addListenerOnce(that.map_, "dragstart", function () { isDragging = true; });
google.maps.event.addListenerOnce(that.map_, "dragend", function () { isDragging = false; });

This solves my marker-cluster-not-clicking problem in some devices.
