Tracked Device Raycaster and World Space Canvases

Using only the Unity Input System and the OpenXR Plugin packages, I want to have UI interaction using the XR controllers and multiple World Space Canvases using the Input System UI Input Module and Tracked Device Raycasters.

This works fine until two or more World Space canvases overlap, in which case the order in which they are interacted with is not determined by their distance to the pointer device, but by their reverse order in the scene hierarchy.

Is there a way to have multiple World Space canvases and to be able to interact with them based on their distance to the pointer device in XR?
