Even though the project is using WebGL2 (OpenGL 3), this might be happening because the API being used is actually WebGL (OpenGL 2). I’m not very familiar with the behavioral differences between these two versions.

Does WASM really need two copies of the non-template assets? You've got this here, and above on line 472 it also copies it into obj/assets.
