jupyter notebook displaying html in iframe causes CORS issue

[Gabriel Bassett]

Hi,

I am rendering a rmarkdown file to html to view in jupyter notebook.  The notebook contains a script to kick off additional analysis in an airflow instance using a JS call to fetch(), however the script is blocked by CORS.  I _think_ I've narrowed it down to jupyter wrapping the html file in an iframe.  How would I go about changing the iframe settings so it has the same origin as the parent page so that the correct origin is picked up by the fetch() call in the script?

Thank you for the help!
