Relevante Passage:
Last April, we introduced the WebVR 1.1 API in Microsoft Edge as part of the Windows Creators Update, providing a foundation for developers to create immersive virtual reality experiences with Windows Mixed Reality developer kits. We have been hard at work building on this foundation to provide an end-to-end mixed reality experience with Microsoft Edge, WebVR, and Windows Mixed Reality, in line with our goal to democratize virtual reality this holiday.
