### Describe the bug Ref discussion #9152 For the upgrader, it has been proposed to add a self-contained **custom layout** to prevent user added elements from showing, e.g: <img width="936" height="287" alt="image" src="https://github.com/user-attachments/assets/41c533e3-6a27-4a4a-b2d8-048e3e27b833" /> <img width="227" height="41" alt="image" src="https://github.com/user-attachments/assets/4ebc2748-af0c-44c8-b6cd-88b284910238" />
