There are issues with for loops in GLSL, see for instance:
https://learnwebgl.brown37.net/12_shader_language/glsl_control_structures.html
The solution is to rewrite the shader so that it also works on WebGL.

The member names in the "uniform block" (which is in practice
mapped to a struct uniform with GLSL) must match between the
vertex and fragment shaders, even if the member is not used in
one of the shaders. This is because OpenGL/GLSL's interface
matching rules, which would cause the shader program fail to
link due to a mismatch in the structs in the two shaders.
Pick-to: 6.1 6.0
