Viewports and Dockspace. Window stops responding to any action. #5503
Description
Version/Branch of Dear ImGui:
Version: v1.86
Branch: docking
Back-end/Renderer/Compiler/OS
Back-ends: imgui_impl_opengl3.cpp + imgui_impl_glfw.cpp
Compiler: Visual Studio 2022
Operating System: Windows 10
My Issue/Question:
Used dockspace and multiviewports.
When the window is detached from the dockspace in a collapsed state, the main window stops responding to any actions.
This problem only occurs while using multiviewports.
Maybe I'm doing something wrong, but it looks like a problem of multiviewports.

I paste this code before ImGui::Render(); in OpenGL3 and GLFW example.
static bool firstLoop = true;
ImGuiWindowFlags window_flags = ImGuiWindowFlags_NoDocking;
if (ImGui::Begin("Shader Editor", nullptr, window_flags))
{
ImGuiID idWind = ImGui::GetID("Shader Editor");
if (firstLoop)
{
ImVec2 workCenter = ImGui::GetMainViewport()->GetWorkCenter();
ImGuiID id = ImGui::GetID("Shader Editor DockSpace");
ImGui::DockBuilderRemoveNode(id);
ImGui::DockBuilderAddNode(id);
ImVec2 size{ 600, 300 };
ImVec2 nodePos{ workCenter.x - size.x * 0.5f, workCenter.y - size.y * 0.5f };
// Set the size and position:
ImGui::DockBuilderSetNodeSize(id, size);
ImGui::DockBuilderSetNodePos(id, nodePos);
ImGuiID dock1 = ImGui::DockBuilderSplitNode(id, ImGuiDir_Left, 0.5f, nullptr, &id);
ImGuiID dock2 = ImGui::DockBuilderSplitNode(id, ImGuiDir_Right, 0.5f, nullptr, &id);
ImGuiID dock3 = ImGui::DockBuilderSplitNode(dock2, ImGuiDir_Down, 0.5f, nullptr, &dock2);
ImGui::DockBuilderDockWindow("One", dock1);
ImGui::DockBuilderDockWindow("Two", dock2);
ImGui::DockBuilderDockWindow("Three", dock3);
ImGui::DockBuilderFinish(id);
firstLoop = false;
}
ImGui::DockSpace(ImGui::GetID("Shader Editor DockSpace"), ImVec2(0, 0));
ImGui::Begin("One"); ImGui::Text("One"); ImGui::Separator(); ImGui::End();
ImGui::Begin("Two"); ImGui::Text("Two"); ImGui::Separator(); ImGui::End();
ImGui::Begin("Three"); ImGui::Text("Three"); ImGui::Separator(); ImGui::End();
}
ImGui::End();
