Map popup alignment

[raymondxu]

On Safari 8.0.4, OS X 10.10.2, the map popups become misaligned after refreshing the page a few times. From testing, the popups also realign themselves after multiple refreshes.

Update: Issue also appears on Chrome.

Seems fixed by #161 for reference.

function checkReady() {
    if (document.getElementById('map').getSVGDocument() == null) {
      setTimeout(checkReady, 5);
    }
    else {
      run();
    }
  }
