Does anyone know what process config property (or combined properties) control the automatic state change of work items to "Resolved" when identified as a duplicate of another work item?

We have a custom workflow for work items in a minimally customized scrum process based project area.  Since pointing the defect work item to the new workflow the automated state change to resolved on defects has stopped.

I would like to understand the exact properties that are in the default Scrum process template that control this behavior for work items.

Thanks,

Chris
