Testing Environment: Windows 11 23H2, MacBook M3 Pro Sonoma 14.6

-According to user investigation they have figured out that OpenXRInteractionFeature for D-Pad interaction is registering control layout replacement for 'Dpad' with type UnityEngine.XR.OpenXR.Features.Interactions.DPadInteraction+DPad instead of UnityEngine.InputSystem.Controls.DpadControl in InputManager.RegisterControlLayout method. Even when this feature is disabled in OpenXR plugin settings, code is executed from OpenXRInput.RegisterFeatureLayouts.
-Error:
InvalidOperationException: Cannot instantiate device layout 'Dpad' as child of '/GamePad'; devices must be added at root
