Unfortunately, the behavior you're observing is due to the way macOS handles window positioning. When you manually drag a window, macOS allows you to position it in a way that partially obscures the menu bar as long as it has a window level that enables that. However, programmatically setting a window's position respects the boundaries of the screen, excluding the menu bar. There's not really anything we can do about this.
