When attempting to launch the WebXR application in Chrome, the rendering of the local origin is not at 0,0,0. The Y offset appears as though it is too high above the ground and as a result the Guardian boundaries are placed above the table in the sample desert scene. When attempting to use the Unity webxr export plug-in on another Unity scene, and launching the application in Chrome, the same issue appears. See https://vr.greyblock.co in Chrome and launch in VR to see bug. Both the sample desert scene and the mentioned sample scene render correctly in Firefox though.
