Elastalert plugin not loading due to CSP error on Kibana 7.3.0

[stevengoossensB]

Since the upgrade to Kibana 7.3.0 and the Elastalert kibana plugin, my browser doesn't load the plugin anymore. I'm using the most recent version of Chrome and am getting the following error in the Chrome debugger. I've tried playing with the newly introduced csp settings in Kibana.yml as a test, but that doesn't change anything.

Any thought on what might be the issue here?
