title: Leaflet drawing tiles disjointly
body: <p>I am instantiating a leaflet map, but the tiles are basically being scattered all over the page - while the map is within a div, most of the tiles are not respecting that boundary:</p>
  
  <pre><code>&lt;div class="widget-content listing-search-map-widget-content"&gt;
      &lt;div class="ih-map" 
           id="Map_5333811_16"
           style="height:450px;"
           data-centerpoint="38.573955 -121.442478" 
           data-mousewheel="true" 
           data-maptype="TERRAIN"
           data-zoom="8"
          &gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The javascript comes down to:</p>
  
  <pre><code>mapOptions = {
                 attributionControl: true,
                 center: {
                     lat: 38.573955
                     lng: -121.442478
                 },
                 centerpoint: "38.573955,-121.442478", 
                 layers: {},
                 maptype: "Terrain", 
                 scrollWheelZoom: false, 
                 zoom: 8
              }
  
  var map = L.map( "Map_5333811_16", mapOptions );
  </code></pre>
  
  <p>What would cause the tiles to plot all over the place?a couple of tiles are within the bounds of the div, but not the rest of them. You can see a screenshot of what happens here:</p>
