Title: Fix for issue#273 map loses focus when zooming in on cluster with keyboard

When a keyboard user tabs to select a cluster and presses enter, the focus is reset such that subsequent tabs start from the top of the page.

When clicking into a cluster, focus is correctly set and subsequent tabs start from the points/clusters shown after the zoom.
