Approval option shown after issue moved/transition to a non-approval status

Summary

When a ticket is moved or transition from an approval-configured status to a non-approval status, the agent view (in Jira) still shows options for approving the ticket (Approve and Decline).

Steps to Reproduce

Scenario 1 (Moving the ticket from a workflow with approval to a non-approval workflow)

1. Modify the workflow from an issue type on a Service Desk Project to require approval, and have at least one issue type on the same project that does not have approval as part of the workflow.
2. Create a ticket on the issue type that needs approval
3. Move the ticket to the issue type that does not require approval

Scenario 2 (Transition a ticket from approval status without setting approval)

1. Create a workflow with approval and create a transition to back from the approval status to the previous status. Publish the workflow.
2. Create an issue and transition to the approval status. Transition it back to the previous status. The 'Approve' and 'Decline' buttons will keep available in the customer portal.

Expected Results

Approval is no longer needed for the ticket

Actual Results

The ability to approve (or decline) the ticket is still shown in the User Interface. Please note that clicking on the 'Approve' or 'Decline' button will not change the status of the ticket.

Workaround

No known workaround
