When map spans larger width than the width of one world map clusters no appear on duplicate map spans

[LukeSkaff]

When the map width becomes wider than one world map the clusters only show on one of the world maps but the pins show up on both. This is a lot easier to describe with a picture...

On the right map North and South America render the pins properly but the clusters do not.

This is by no means a typical application of a map and you are probably wondering why in the world I am doing this, I am using a map on a page as a full width "row" on a site for a nice visual effect.

The normal single point pins are shown for both but not the clusters, I am trying to track down in the code where the bounds are stopping the clusters from rendering on both maps any nudging the right direction would be a huge help.

Cheers,
