Wireframe render is incomplete

[remcoder]

When selecting wireframe mode in the dev panel, some parts of the model seem to be missing.

I have a suspicion this bug has the same root cause as #216

It's all about lines rendered.

I've been investigating for a while, trying to eliminate causes. _wireframe is just a boolean passed to the material and does not have logic attached to it. I've ruled out rerender logic, as it happens also on the initial render.

I've tried playing with the WebGLRenderer's and scene settings, as well as changing material type and line settings. It happens anyways.

Could it be a bug in Three.js?

There's an interesting issue in the Three.js repo: mrdoob/three.js#29045
