Possible bug: An upper limit on the number of vertices in a MeshLine

[turner]

I intended to use MeshLine for a genomics visualization app I am writing but ran into a significant bug. I stumbled across an upper limit on the number of vertices. That number is somewhere around 131370 vertices. I used demo/shape.html to zero in on this.

Here is a visual with partially decapitated head model:

Has anyone else seen this?
