Resolution Note (fix version 1.0.0-pre.2):
The problem was caused by the project adding a Grab Interactable component to a parent GameObject that shares Colliders with the child Grab Interactable. However, the initial child Interactable would only unregister from the Interaction Manager during OnDestroy, which is invoked later after the Destroy call. When the new Grab Interactable was registered with the Interaction Manager, its Colliders list conflicted with the still registered child Interactable.
With changes made with 1.0.0-pre.2, the Interactable will unregister during OnDisable, which is invoked immediately. The new Interactable is thus able to associate the Collider with it.
