The top-left option implies it will maximise the window.  When maximised, the titlebar buttons should look like so <img width="130" height="44" alt="Titlebar - expected result" src="https://github.com/user-attachments/assets/86c4cf3d-2b6a-4fff-9747-e9c845858bc0" /> However, they look like this <img width="134" height="46" alt="Titlebar - Actual result" src="https://github.com/user-attachments/assets/229e72e5-9b73-42ef-8368-c0a6a52c5bb6" /> Meaning that the window is still floating i.e. not maximised.
