Can't open filters in non-exclusive FileDialog

[L4Vo5]

Godot version

v4.1.rc3.official [cdd2313]

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

For future reference, please also include the godot.project-file in the MRP. The .tscn-file is usually not enough, because it lacks project-specific information.

When testing this with embedded windows enabled, I can confirm the problem. (#78476 addresses part of this problem, but I doubt, that it is enough to solve it)
When testing this with embedded windows disabled, the FileDialog simply closes after clicking on All Files (*).

My guess is that this got introduced in #78363.

A workaround is to set the AcceptDialog option Close on Escape from On to Off.

Oh, I tested it on a blank project, so I didn't think that file would matter.

Thanks for the workaround!
