Per spec:
"Additionally, exporting a fence payload to a handle with copy transference has the same side effects
on the source fence’s payload as executing a fence reset operation. If the fence was using a
temporarily imported payload, the fence’s prior permanent payload will be restored."
And similar for semaphores:
"Additionally, exporting a semaphore payload to a handle with copy transference has the same side
effects on the source semaphore’s payload as executing a semaphore wait operation. If the
semaphore was using a temporarily imported payload, the semaphore’s prior permanent payload
will be restored."
