The label of the operation button should appear as mandatory on creation

In Nuxeo Studio Designer, when a user creates a new button linked to an automation chain / scripting, the "Label" field is not indicated as mandatory. If the user saves, it raises an error asking the user to fill in the label (then the red star appears on the field). 

Expected behavior: the field should be clearly indicated as mandatory right from the start

Only happens when you create a new entry
