Unity + OpenXR + OVRSpatialAnchor + Passthrough = Wobbly models

Previously we were using the Oculus XR Plugin with OVRSpatialAnchors and passthrough and all was working as intended. We needed to switch from the Oculus XR Plugin to OpenXR (for a separate package) ...

I built a minimal project with the least amount of things needed to get this to reproduce. To reproduce it I just need to have a GameObject with the OVRManager script and Anchor Support enabled. Once I remove the OVRManager script the wobblyness goes away (and I'm assuming the functionality of the OVRSpatialAnchor's). Therefore passthrough is not the cause of the wobblyness.
