Open an URL webpage in a iframe while inside VR mode on an app

Hello,

I created a guide 360 tour, and inside there are a hotspot that open an iframe with an URL home page.

When I am on any browser, it opens normally, but when I go to the VR mode, doesn't work. 

Someone told me that this is a VR world "restriction", please, is anyone having the same problem?

Many Thanks in Advance
