</script>

What steps will reproduce the problem?
1. Build a map with a marker cluseterer and google maps view
2. View in satilite view
3. Switch to earth view

Expected result:
The marker clusterer should be viewable in the earth view

Actual result:
The marker clusterer disappears and only the markers that were visible are now 
visible in the earth view

Version: 2.0.8

Browser / Operating System:
