PopupMenu with prefer_native_menu=true does not emit popup_hide signal on Windows

[marcelovbcfilho]

Tested versions

v4.3.stable.mono.official [77dcf97]

System information

Godot v4.3.stable.mono - Windows 10.0.26100 - Vulkan (Forward+) - dedicated AMD Radeon RX 6800M (Advanced Micro Devices, Inc.; 32.0.12033.1030) - AMD Ryzen 9 5980HX with Radeon Graphics (16 Threads)

Issue description

• When using PopUpMenu to create a right click context menu with prefer_native_menu set to true the popup_hide signal is not emitted.
• On MacOS with prefer_native_menu set to true the popup_hide signal is emitted as expected.
• Also when prefer_native_menu is set to false the popup_hide signal is emitted as expected.

Steps to reproduce

• Create empty project
• Add some Buttons
• Add a PopUpMenu with prefer_native_menu=true
• Add a script that when right click on button calls the PopUpMenu popup() mthod
• In the same script connect the popup_hide signal to a function
• Dismiss the PopUpMenu by clicking somewhere else
• Signal should be emitted

Searched around the source code and this maybe isn't a bug, but a missing feature, the set_popup_close_callback method that is used to emit the popup_hide signal is marked as not supported in the windows specific implementation.

godot/platform/windows/native_menu_windows.cpp

Lines 202 to 204 in 2582793

	void NativeMenuWindows::set_popup_close_callback(const RID &p_rid, const Callable &p_callback) {
	// Not supported.
	}
