### Godot version

v4.1.rc3.official [cdd2313ba]

### System information

Godot v4.1.rc3 - Windows 10.0.19045 - Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz (8 Threads)

### Issue description

Trying to open the filters (file types) menu in a non-exclusive FileDialog makes it automatically close and brings up the following error in the console/debugger:
```
ERROR: Condition "!windows.has(p_window)" is true. Returning: Rect2i()
   at: window_get_popup_safe_rect (platform/windows/display_server_windows.cpp:2426)
```
This seems to have been broken somewhere between 4.1 beta 2 and beta 3.

### Steps to reproduce

- Create a FileDialog
- Untick the "Exclusive" box
- Make it visible / pop it up / etc
- Try opening the `All Files (*)` menu
