title: React Virtualized List with AutoSizer - vertical scrollbar does not appear
body: <p>I am trying to use React Virtualized List together with AutoSizer.
  This is my problem: I set the height of the list to be 200px, and then I see in the Chrome inspector that the height is 200, which is OK, but the overflowed content are visible even though I see that the css style of ReatVirtualized_Grid_innerScrollContainer are sat to overflow: hidden. The problem causes no vertical scroll bar and are displaying a big part of the data, but not all. So it displays a lot more data than the specified height I've sat. Why is that?</p>
  
  <p>This is my code:</p>
  
  <pre><code>import Row from './Row';
  ...
  render () {
    return (
      &lt;AutoSizer disableHeight&gt;
       {({ width })} =&gt; (
         &lt;List
            height={200}
            width={width}
            rowCount={this.props.list.size}
            rowRenderer={this.rowRenderer}
            rowHeight={24}
          /&gt;
        )}
      &lt;/AutoSizer&gt;
    );
  }
  rowRenderer = ({ key, style, index, parent }) =&gt; {
    const row = this.props.list.get(index);
    return (
      &lt;Row
        row={row}
        style={style}
        rowIndex={index}
        parent={parent}
        columnIndex={0}
      /&gt;
    );
  }
  </code></pre>
