OpenVR 5.4.0f2: UnityEngine.VR.VRDevice.isPresent is inconsistent with OpenVR + Rift CV1

2. How we can reproduce it using the example you attached

1) Setup CV1
2) Ensure Open VR is the preferred SDK in the VR SDKs list in Player Settings
3) Now hide the CV1 from the tracking camera so that SteamVR reports "Headset not tracking" and "Not Ready"
Note: Getting SteamVR in this state can be a little finicky so be patient and if it doesn't get in that state for a while after hiding the headset, try rebooting Oculus Home and SteamVR. Also see the attached screenshot for the expected SteamVR state.
4) Once the headset is hidden and not tracking enter playmode.
5) Observe that VRDevice.isPresent is reported as false in both the Awake and Start functions

Expected result:
UnityEngine.VR.VRDevice.isPresent shouldn't return false if the HMD is connected and merely occluded from the view of the basestations/cameras.
