Right now if you select a cluster and click 'zoom,' the map doesn't actually zoom. It just pans to the selected cluster. More than likely, the feature that's selected would already be in the display, so not only is this counterintuitive to what "zoom" means, it's fairly useless. It would be more useful and intuitive if it actually zoomed, revealing the individual features within the cluster.
This works fine within Map Viewer.
