Description

This is reproduced when building a new flow:

• Add GenerateFlowFile
• Add AttributesToJSON
• Connect Generate -> AttributesToJSON
• Don't start anything
• Right click the connection -> Empty queue, confirm when prompted

Expected: either no action (stopped empty queue, 0 entries) or action performed and dialog dismissed.
Actual: the modal dialog shows 100%, 'Completed Successfully' message, the button says 'Stop' and there's no way to dismiss the dialog until after a complete UI reload.
