Revert of WebVR: fix focus while presenting (patchset #1 id:1 of https://codereview.chromium.org/2847233002/ )
Reason for revert:
So there are a bunch of problems with this CL.
1. Now third-party iframes can just arbitrarily read head pose without needing focus as long as the main page has focus.
2. We've just broken the assumption that only one VrDisplay can be focused at a time. If the page has two iframes that want poses, and one presents, they're now both going to be fighting with each other to get the pose information.
Original issue's description:
> WebVR: fix focus while presenting
>
> If the WebVR document loses focus, check if the new focused element is an
> embedding local parent frame. If that's the case, continue presenting. This
> fixes issues with Cardboard-style touch events that are reported as a click at
> viewport (0, 0) where the resulting focus loss stopped presentation.
