Description

Like the old library the current one has the problem that on some aspect ratios of the map the click handler on a cluster does not zoom in.

https://github.com/googlemaps/js-marker-clusterer/issues/135

The is reproduceable in the examples. When you define a small height for the canvas like 200 pixels or so. In my page it does not work for a width of 850 px and a height of 250 pixels. When I use a height of 500 pixels everything is fine.

Research direction
Investigate the click event handling in MarkerClustererPlus source code. Focus on how the cluster's click target is determined and whether map dimensions affect the hit detection.
