Assertion failed in menu.

Version/Branch of Dear ImGui:

Version: 1.84.2
Branch: master

Back-end/Renderer/Compiler/OS

Back-ends: win32 dx9
Compiler: vs2019
Operating System: Windows 10

My Issue/Question:

ImGui::FindWindowFocusIndex
IM_ASSERT(g.WindowsFocusOrder[order] == window);

window->Name: ##Menu_01
window->FocusOrder: 0

g.WindowsFocusOrder
Size: 4
[0]: Debug##Default
[1]: Hello, world!
[2]: Dear ImGui Demo
[3]: ##Menu_00

The release version doesn't crash, but it does force the 'Menu' to close.

Thank you for reporting this!
Confirmed repro (was easier to repro by resizing the host window down so the menus would be pushed back toward the left), will investigate

Pushed a fix ba5c105. Thanks for reporting this!

Which while debugging also led me on a tangent of thinking the value of OpenPopupStack[n].SourceWindow may be inadequate for some uses since bda2cde and #2517, but actually it makes sense that it would record the last focused window here (the Colors menu, 4th in the stack in your gif). Right now I can't find another issue I'm just writing this down and linking the issues # for future reference.
