Regression

No

Black screen on startup and an endless loop of xrLocateSpace errors when "Not Specified" & "Floor" Tracking Origin is used

Package: OpenXR Plugin

-

Steps to reproduce:
1. Create a new VR Template Project
2. Switch Platform to Android
3. In XR Management enable OpenXR and disable any XR Feature, like Meta support, etc (customer wants to use the Standard Khronos OpenXR Loader)
4. In the XR Rig change the Tracking of the Headset to Floor
5. Build APK and deploy on HMD
6. Results in a black Screen and OpenXR errors

Expected result: no black screen and no OpenXR errors
Actual result: application enters a loop asking for xrLocateSpace with an invalid handle from which it never recovers

Reproducible according to the customer: OpenXR 1.13.0 - 1.15.1 (6000.1.8f1)
Not reproducible according to the customer: OpenXR 1.12.1 (6000.1.8f1)
Could not test on all currently supported streams due to missing required hardware

Notes:
-Do note this was not reproduced by CQA due to missing Android VR hardware
-"Unity6.1_1.4.3_OpenXR-Plugin.logcat" is provided by the customer
-In the log at line 398 you should see the list of OpenXR extensions the device reports as supported
-At line 367, we can see 2 calls to xrCreateReferenceSpace that fail with XR_ERROR_REFERENCE_SPACE_UNSUPPORTED
-Additional behavior was observed by the customer:
"Not Specified" & "Floor" Tracking Origin result in the endless loop of xrLocateSpace failures and never recovers -> Black Screen.
"Device" & "Unbounded" Tracking Origin will initially give the same errors until it will eventually start rendering (and the errors stop) but the height is predefined from the Inspector.
