1306434 - [webvr] Implement the `navigator.vrEnabled` and `allowvr` iframe attributes

Status: NEW

(Core :: WebVR, enhancement)

Description

[:kip (Kearwood Gilbert)]

The WebVR 1.1 spec defines how iframe content will be given permission to use WebVR devices.

We must implement the Navigator.vrEnabled attribute and the allowvr iframe attribute:
https://w3c.github.io/webvr/#navigator-vrenabled-attribute
https://w3c.github.io/webvr/#dom-htmliframeelement-allowvr

I am moving this to be a dependency of WebVR 1.2, as there is still active discussion in the WebVR implementer meetings, that could affect the specification.

This can go out with 1.2, per discussions with implementers.

Any update on this? I'm interested in showing off the power of Firefox Nightly + Vive / Rift but currently it seems like Nightly freezes when "vrrequestpresent" is invoked from an iframe with allowvr. I can make an example if it's helpful.

WebVR has been deprecated, and such functionality is anticipated to be later added to the successor, WebXR spec.

The bug assignee didn't login in Bugzilla in the last 7 months, so the assignee is being reset.
