Description
I am trying to represent random points on a map using superclusters and mapbox.
I ran into an issue while testing for the two points: [ -60.44, -1.77] and [-55.44, -5.77]; running getClusters with a supercluster instance set up as follows:
const index = new Supercluster({
log: true,
radius: 20,
extent: 256,
maxZoom: 3
})
Returns a single point (not cluster of 2) at zoom > 5

Research direction
Start by reproducing getClusters with the two coordinates and the shown Supercluster options, including the reported zoom levels. Then inspect the clustering implementation and determine why two points produce zero or one result; done means the behavior is explained and a focused regression test confirms the expected result.
