Open Notifications in Worklist

Need feedback on below scenario and would like to understand how Oracle should behave ?

- User created Purchase Requisition in iProcurement.

- Submitted the requisition multiple times for approval within span of few seconds.

- Approver received multiple email notification. Same can be viewed in work list as well.

- Approver approved via one of the email notification.

- Purchase requisition status changes to approved.

- Still see remaining notification in open notification section of the work list for same requisition.

In such scenario, shouldn't other open notification get closed automatically (in work list) when corresponding approver approves it via one of the email notification ?
