Description (partial)

'port-mode' config applied to a nV Optical Optics controller is rejected if
committed at the same time as the controller being deleted.

For instance, the 'no transponder' config below causes the Optics100/3/0/1
controller to be deleted, and the port-mode config to be rejected.

The expected behaviour is that the 'port-mode' config is moved to
preconfiguration under the deleted controller.

Seen in any scenario that causes 'port-mode' config to be added or changed on
an Optics controller that is being deleted.

In particular, it's possible to see this behaviour during config rollbacks.
