Opening native file dialog on Windows makes the base window unresponsive

[KoBeWi]

Godot version

4.2 0c2144d

System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

Issue description

When you use DisplayServer.file_dialog_show(), Godot freezes until the dialog is closed:

godot.windows.editor.dev.x86_64_6xtybPE0Bk.mp4

For reference, here's how Chrome handles it (🔊):

Steps to reproduce

1. Run this on Windows

@tool
extends EditorScript

func _run() -> void:
	DisplayServer.file_dialog_show("Dialoog", "C:/", "", false, DisplayServer.FILE_DIALOG_MODE_OPEN_FILE, [], Callable())

2. Click Godot like crazy until it dies
