Like I said, the FCTM says you shouldn’t do it for the for those obvious reasons. I see lots of guys putting it back into managed climb if it reverts to open climb after finishing the SID.
As for the original topic, it seems to happen pretty consistently. If you’re in ALT with a high speed and pull for OP CLB, then wind the speed back, thrust rather inappropriately comes back. Not sure why this would be a ‘feature’ of the airbus though? I can’t find anything in the FCOM. If you select a higher speed then pull the speed back I think it keeps the thrust on like it should.
