Ok. The example was an artificial one. A real problem that I experience is 
that if you have multiple sagecell instances (with separate input and 
output elements) in one web page, you have jsmol graphics intefering with 
each other.

I agree. I think we should switch to threejs at a point when threejs in 
sage is mature enough, even though not perfect...

Thank you for clarifying the situation!
