When using the limit_output nbextension, any executed code cell prints out the warning message "limit_output extension: Maximum message size exceeded", independent of the char count for the output.
Below is a screenshot of the issue, where i configure a limit of 1000 chars and print "problem", still getting the warning when clearly it is less than 1k chars.
Screenshot of issue:

Setup:
I am working off the jupyter/scipy-notebook docker image, installing the extensions and enabling them when building a new docker image.
