### Godot version

v4.1.beta3.official [ada712e06]

### System information

Godot v4.1.beta3 - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 (NVIDIA; 31.0.15.3623) - AMD Ryzen 9 7950X 16-Core Processor (32 Threads)

### Issue description

Related: #77378 (Might be caused by this).

When a project is launched with `display/window/size/mode` set to `Fullscreen` the main window will instead open in `Exclusive Fullscreen`. Moving the window in place seems to fix this, but I'm hesitant to call that a proper solution:

I.e. add `MoveWindow(...)` after creating the window here (or during it):

It might be enough to send one of the messages that `MoveWindow` does https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-movewindow#remarks but I haven't tested.

### Steps to reproduce

Open a project on Windows with `display/window/size/mode` set to `Fullscreen`.
