Cloud Display inside cluster shows with points

Cloud Display for Cluster (126.7 KB)

[Rhino 8]
I like to use the Cloud Display inside cluster with the Preview Contents enabled.
The problem is, the cluster shows the Cloud Display along with the points.
The gray dots in the whites, I like them to hide.

In contrary, if you use Cloud Display outside of cluster, there will be no issue.

I can use the Custom Preview, but that is too costly.
