- Go to the edit screen for any blueprint
- Hover over the edit button : no tooltip
- Click the edit button to open the textfield
- Hover over the edit button again : tooltip saying "Save label"
- Confirm or cancel the name by clicking the edit button (now the save button), pressing enter, or pressing escape
- Hover over the edit button again: tooltip still says "Save label"
