iFrame new tab links

[ados8]

I have iFrame working, well sort of.
Glance operates ok within the iFrame and within that constraint there's no issues.
However, once you open a link which opens a corresponding new tab that link has issues with iFrame errors on sites.
I'm wondering if this is a configuration error on my part or Glance not handling iFrames appropriately.
I'm using NGINX with CSP for iFrame.
