This issue seems to still exist in some situations. If the vertical mail viewer is used and you gradually reduce the width of the message pane the "more" icon will be triggered even before any buttons have disappeared. This results in an empty more menu. As the pane is narrowed further a button will disappear and then the more option is populated with that button.
