title: Updating multiple rows on a large handsontable locks chrome
body: <p>I have a handson table with 300+. It renders quickly. However, if I update one column in all rows like so:</p>
  
  <pre><code>function() {
      console.trace("Start", new Date());
      $scope.myData.forEach(function(elem, idx) {
          elem.properties.myCol = Math.random();
          if (idx % 100 == 0) console.trace("Tick", new Date());
      });
      console.trace("End", new Date());
  };
  </code></pre>
  
  <p>The loop executes in less than a second, but the browser tab locks up and the page does not update for over a minute. Is there some way I can disable handsontable from reading updates to the array and then triggering a manual redraw? Is there any other way to speed this up?</p>
