It's probably not possible. Pay attention to the fact that looktohotspot() in VR is a mistake. This destroys the immersion effect and can lead to confusion. In the real world view does not rotate itself. You need to turn your head.
Thanks for your input. I thought it was more like the like the littlebigplanet intro, which I thought is possible in webvr, no? And this is a bit like how I'm trying to use it, like an intro to a scene to take a user to their intended start location while providing some bearing on the scene.
I essentially want to turn set(control.usercontrol, off); during initial load, then turn on, onloadcomplete
And is little big planet possible for entering a new scene? Or only available on initial load?
