Messenger window taller than the screen at 150% scaling, so the header is cut off

On a Dell Latitude 5330 (1920×1080, Windows 11, scaling 150%, which is the Windows recommended default), Gorelo Messenger opens docked to the right with its top cut off. The header, including the minimise and close buttons, sits above the top of the screen, so users can’t drag, minimise or close the window with the mouse.

At 150% the usable screen is about 1280×720, or roughly 670 high above the taskbar. Messenger seems to open at a fixed height taller than that.

Changing display scaling isn’t an option for us. 150% is the default on this hardware and staff need it. Every laptop in this client’s fleet is the same model, so all of them will hit this.

Expected: the window fits the usable screen area, by sizing to the work area or capping its height at it, and stays fully on screen.
