setMaterial breaks in Chrome Mobile Android

[figuernd]

This only applies to Chrome Mobile Android; desktop (even in Developer->Mobile mode) cannot reproduce this.

Symptom: Swapping textures via api.addTexture and api.setMaterial results in no texture at all on the mesh.

To reproduce: Open this JSFiddle in Chrome Mobile and attempt to swap textures. Again, must be done on Chrome mobile on an Android device. https://jsfiddle.net/PadreZippo/n06vewm9/
