How to add allow-top-navigation to power bi embedded

I've created a custom visual that generates a hyperlink based on a slicer selection.  I've imported the custom visual to my PBIX in Power BI desktop and have published this to my workspace (note: workspace, not power bi service) in order to embed this report in my custom web application.  Because the iframe for my custom visual does not have allow-top-navigation enabled, I'm getting a javascript security error when clicking the link.  How can I fix this?
