Ribbon - Clicking a tab group's caption button does not raise the button's OnClick event if the Ribbon control's ShowTabGroups property and the bar manager's HideFloatingBarsWhenInactive property are set to False

If BarManager.HideFloatingBarsWhenInactive is False - CaptionButtons of RibbonGroups (Toolbars) does not work anymore if Ribbon is collapsed.
The click is just not accepted! This is why:

procedure TdxBarDockedControl.WMNCLButtonDown(var Message: TWMNCLButtonDown);
begin
  …
  AActiveButtonID := GetCaptionButtonIndex(GetWindowCursorPos);

if AActiveButtonID <> -1 then
  begin
-> This closes the Ribbon popup window too! -> Button disappears from screen
    if not BarManager.HideFloatingBarsWhenInactive then
      SetActiveWindow(BarManager.Owner.Handle);
…
          case message of
            WM_LBUTTONUP:
              begin
-> This fails cause of the missing Button under cursor!
                ASuccessfulDragging := GetCaptionButtonIndex(GetWindowCursorPos) = AActiveButtonID;
                Break;
              end;

To reproduce just disable HideFloatingBarsWhenInactive in the BarManager of your RibbonNotepadDemo.
Run, collapse the Ribbon and try one of the CaptionButtons.
