These two tests depend on the existence of WebXR. Safari on macOS fails these subtests because WebXR is not supported on Mac.
A dependency on an unrelated technology that's not core to the focus area shouldn't be a blocker. Ideally, these tests would be run on the appropriate platform — for Safari that would be visionOS. But since that's not possible, these two tests should be unlabeled and not included in Interop 2024.
