I'm doing homework, and I don't have time to troubleshoot this. Check the
preconditions. If cell_div.className != 'cell_div_output_wrap' to begin with,
it would exibit the behavior that Andrey and I are experiencing. It's strange,
though. I get the incorrect behavior sometimes, and not others. Later this
week, I'll try to hunt this down.
