Issue Summary

Confluence page with embedded JavaScript to render an SVG graphic of a .json file attached to that page is not showing the image on Chrome and Firefox browsers. It appears to be working fine in IE and Edge browsers. In Confluence version 6.10.2, all browsers are able to render the same without any issues

Environment

Confluence 6.14.3

Steps to Reproduce

1. Create a blank Confluence page
2. Ensure the site has the Confluence Source Editor plugin installed and you have permission to use the source editor.
3. Open the source editor and paste the storage format attached.
4. Apply and upload the changes

Expected Results

If you open the page in IE you see the SVG image 

Actual Results

if you open it in FF or Chrome nothing is shown (see attached screenshots) and no errors in the logs.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
