title: What is the component a popup menu click originated from
body: <p>Having a popup menu attached to several components on a form (buttons, but also things like TCharts), I would like to know which component was right clicked to start the popup menu in the first place.</p>
  
  <p>The Sender parameter of the click method just points to the TMenuItem, its parent to the popup menu (or the parenting menu item).</p>
  
  <p>How do I get the originating component?</p>
