While a popover is hiding, the modal grab is already gone and the toggle button is clickable again, but clicking again at that time will result in gtk_widget_show() trying to show an already shown widget (although fading out and hidden soon) and the toggle button activated. So let the menubutton set the active status only if the menu/popover widget wasn't already shown, and ensure this doesn't get triggered by double/triple button press events.
