Python interpreter only returns 1000 rows even if config max_results is set higher

Python paragraphs with visualisations/exports never return over 1000 rows, irrespectively of the configuration setting in conf/zeppelin-env.sh :
export ZEPPELIN_SPARK_MAXRESULT=2000

It looks like PythonInterpreter uses hardcoded value [1] instead of reading max_result from interpreter property.
