title: Leaflet center popup AND marker to the map
body: <p>I want center my marker on popup open.. and centering map not in marker latlng, but on center of marker and popup!
  The problem is that popup has dinamic content(loaded on click).</p>
  
  <p>The map size is full display size in a mobile device!
  I'm just used autoPanPadding option in popup but not sufficient</p>
