If CSI report slot falls on ack/nack slot then shall UE drop csi report?

Hi 5G/LTE Experts.

If CSI report slot falls on ack/nack slot then shall UE drop csi report?

I think so.
They are given higher priority.

So why UE recieves in its RRC reconfig that csi to be transmitted on S slot where ack/nack defined?
