### Godot version

v4.0.2.stable.official [7a0977c]

### System information

Window 10

### Issue description

If your project is set to `WINDOW_MODE_FULLSCREEN` in project settings, the first time you try to switch mode for `WINDOWED`, it will not switch properly.


### Steps to reproduce

1. Create a new project
2. Change project settings `Display > Window > Mode` for `FullScreen`
3. Run the following code :

Code that reproduce the issue:
```
func _ready():
	DisplayServer.window_set_mode(DisplayServer.WINDOW_MODE_WINDOWED)
	DisplayServer.window_set_size(Vector2i(800,600))
``` 

## Workaround
Calling the `window_set_mode` twice solve the issue...

```
func _ready():
	DisplayServer.window_set_mode(DisplayServer.WINDOW_MODE_WINDOWED)
	DisplayServer.window_set_mode(DisplayServer.WINDOW_MODE_WINDOWED)
	DisplayServer.window_set_size(Vector2i(800,600))
```
