title: missing vertical scroll within ListView xaml uwp
body: <p>am new in UWP and need to do a navigation drawer using <code>SplitView</code>, so my basic layout structure is mentioned below. The problem is that I don't have vertical scroll for list items, maybe I miss some params, any help is appreciated.</p>
  
  <pre><code> &lt;SplitView
      x:Name="MySplitView"
      DisplayMode="CompactOverlay"
      IsPaneOpen="True"
      CompactPaneLength="50"
      OpenPaneLength="280"&gt;
  
      &lt;!--navigation drawer--&gt;
      &lt;SplitView.Pane&gt;
          &lt;StackPanel
              Background="Gray"&gt;
  
              &lt;StackPanel&gt;
  
                  &lt;ListView
                      x:Name="DrawerListOptions"
                      SelectionChanged="MySelectionChanged"
                      SelectionMode="Single"
                      ScrollViewer.VerticalScrollBarVisibility="Auto"&gt;
  
                      &lt;ListView.ItemTemplate&gt;
                          &lt;DataTemplate&gt;
  
                                      &lt;TextBlock
                                          Text="{Binding Title}"
                                          FontSize="18"
                                          Margin="5,0,0,0" /&gt;
  
  
                          &lt;/DataTemplate&gt;
                      &lt;/ListView.ItemTemplate&gt;
                  &lt;/ListView&gt;
  
              &lt;/StackPanel&gt;
  
          &lt;/StackPanel&gt;
  
      &lt;/SplitView.Pane&gt;
  
      &lt;!--page stuff--&gt;
      &lt;SplitView.Content&gt;
           &lt;!--page code--&gt;
      &lt;/SplitView.Content&gt;
  
  &lt;/SplitView&gt;
