For the sake of easily understanding the issue please provide a live example that doesn't require pulling and running a separate Github project. You can host a demo page with...

Thanks for producing a live link. I think this demo is too complicated to dig into, though. There are over 800 individual meshes and a mix of batched and instanced...

I've made a simpler example that just uses javascript and cubes to understand things a bit better. This demo allows for changes between a merged geometry, batched mesh, and instanced...
