Completing a parent activity does not ask for confirmation only if done by the open activity

If you complete the status of a parent activity, all related sub-activities are also completed.
If this change of state is made from inside the open tab, the warning is not shown and no further confirmation is requested.
Confirmation is always requested (see attached image) if the same operation is done without opening the tab of the parent activity (e.g. right click on the activity -> complete or click on the Complete button in the Actions column or click on the button in the window preview).

Steps to reproduce:

• Create parent tasks with child sub-tasks
• Open Parent Task
• Change status to "Completed"
• Click on "Save & Close"

Expected behaviour

• Confirmation is requested that the operation will also be applied to the sub-tasks

Actual behaviour

• No confirmation is requested and all sub-tasks are also changed as completed
