Details:
When using more than one Begin/EndChild pair for the same window a call to IsItemHovered() doesn't return true when that window is hovered. The hovering or last item state seems to be reflecting the item created before the last Begin/EndChild pair.
For example, this code results in the GIF below
ImGui::BeginChild("My Window", ImVec2(200, 100));
ImGui::EndChild();
ImGui::Button("Button");
ImGui::BeginChild("My Window", ImVec2(200, 100));
ImGui::EndChild();
if (ImGui::IsItemHovered()) {
ImGui::SetTooltip("I Expected My Window");
}
I would expect IsItemHovered() to refer to the window and not the button, is that not the case?
