title: Google maps v3 markers over infobox
body: <p>I am creating website <a href="https://yachtcharterbook.com" rel="nofollow">https://yachtcharterbook.com</a> with google maps v3 in it. I got markers and infowindows which popups on marker mouse over. When infowindows appears i try to navigate over it by mouse but when another marker is under it - current infowindow closes and second one popups. There is problem with layers or panels or z-index i dont realy understand. I tryied playing with infowindow pane: 'floatPane', pane: 'mapPane', zIndex on infowindow and markers but no changes. Maybe you have some ideas why it is happening ?</p>

                  position: latLng,
                  map: map,
                  icon: defIcon
              });
  
              var infobox282 = {
                  content: document.getElementById('infobox282'),
                  disableAutoPan: false,
                  maxWidth: 0,
                  pane: 'floatPane',
