Begin() to append doesn't set LastItemData for title-bar/tab (was `BeginItemTooltip` may react to wrong widgets?) about imgui HOT 2 CLOSED

// We fill last item data based on Title Bar/Tab, in order for IsItemHovered() and IsItemActive() to be usable after Begin().
// This is useful to allow creating context menus on title bar only, etc.
SetLastItemData(window->MoveId, g.CurrentItemFlags, IsMouseHoveringRect(title_bar_rect.Min, title_bar_rect.Max, false) ? ImGuiItemStatusFlags_HoveredRect : 0, title_bar_rect);

// When reusing window again multiple times a frame, just append content (don't need to setup again)
if (first_begin_of_the_frame)
{
    ....
}
else
{
   // Append
   SetCurrentWindow(window);

   ImRect title_bar_rect = window->TitleBarRect();
   SetLastItemData(window->MoveId, g.CurrentItemFlags, IsMouseHoveringRect(title_bar_rect.Min, title_bar_rect.Max, false) ? ImGuiItemStatusFlags_HoveredRect : 0, title_bar_rect);
