title: Apache Superset ENABLE_JAVASCRIPT_CONTROLS is true in config.py/superset_config but does not work
body: <p>I have set &quot;ENABLE_JAVASCRIPT_CONTROLS&quot; to true in config.py file and even added ENABLE_JAVASCRIPT_CONTROLS: True in superset_config.py and then restarted Superset Apache. However, it still shows that I can't use javascript and is still grayed out.</p>
