Expected Behavior

Single cluster should be shown representing the constituent points.

Actual Behavior

At certain zoom levels (e.g. 12) there are duplicate features in the clusters, but they don't exist in clusters returned from the server side query. I have included the point identifiers (crashids) in the cluster attributes for reference. I am using ST_AsMVT to create the proto buffer on the server side currently.

I have added a screenshot of what the map looks like loading on my 1080p monitor below:

P.S. I don't know if it is related, but I noticed the same behavior when vectorizing clusters using Supercluster on the server side as well. For that implementation I was using vt-pbf to create the proto buffers.

Start by reproducing the behavior in the linked demonstration with mapbox-gl-js 2.4.1 in Edge, focusing on zoom level 12 and the displayed cluster attributes. Compare the rendered features with the server-side results generated through ST_AsMVT, and also consider the reported Supercluster and vt-pbf setup. Done means the duplicate features no longer appear and the single displayed cluster matches the constituent points.
