title: Highcharts 3d bar chart data labels position is wrong
body: <p>I need to show bar chart with data labels.
  When it is 2d, all is fine.
  But when I show it as 3d bar the data labels position get wrong.
  The code below:</p>
  
  <pre><code>$('#container').highcharts({
      chart: {
          type: 'bar',
          margin: 75,
          options3d: {
              enabled: true,
              alpha: 35,
              beta: 15,
              depth: 110
          }
      },
      plotOptions: {
          bar: {
              depth: 40,
              stacking: true,
              grouping: false,
              groupZPadding: 10,
              dataLabels:{enabled:true}
          }
      },
      series: [{
          data: [1, 2, 4, 3, 2, 4],
          stack: 0
      }, {
          data: [5, 6, 3, 4, 1, 2],
          stack: 0
      }, {
          data: [7, 9, 8, 7, 5, 8],
          stack: 1
      }]
  });
  </code></pre>
  
  <p>});</p>
