Embedding a Power BI report inside a Power Bi report

[UNICODE]

I am trying to embed a Power Bi report inside another report.   
I had the wonderful Idea that I could use the  HTML Content custom visual (@dm-p) to allow this to happen. 

HTML Content - Custom Visual for Power BI (html-content.com)

I am using a BI RS server and I can embed can get reports to embed into share point and html files buy using a <iframe src=https...?rs:embed=true> reference.  Using this same reference in a measure and adding it to the HTML Content visual will not allow me to view the linked report in either the RS Desktop app or when its published to the RS server.  

I'm not understanding why this isn't working, the top level report loads but the linked report justs becomes the circle of spinning dots.  Is this a limitation inside of BI, or a security setting that needs to change on the RS server? 

Thanks for any help

Hi @UNICODE,

Custom visuals themselves are hosted as an iframe, which is sandboxed to have minimum privileges, in order to preserve safety and security as much as possible for end users. As such, these iframes don't have the necessary permissions to handle requirements like cookies and endpoint security to embed an application that will require authentication, like Power BI itself. Any iframes you host inside a custom visual inherit these restrictions irrespective of how you configure their sandbox attributes yourself (if you might think of that next). Using a custom visual (whether it be HTML Content or developing your own would not be a viable solution for this use case, unfortunately.

At best, all you could do would be to link or drill through another report using native Power BI functionality.
