title: TextBox for WP7 limit in text ? bug?
body: <p>I have a TextBox, in which I set the content programmatically :</p>
  
  <blockquote>
    <p>LegalTextBlock.Text = "Some awfully
    long legal content";</p>
  </blockquote>
  
  <p>(see here for a Lorem Ipsum sample that illustrate my problem : <a href="http://pastebin.com/jWLrwcGe" rel="nofollow">http://pastebin.com/jWLrwcGe</a>)</p>
  
  <p>The test is about 4k characteres long, and is not displayed completely. Is this normal ? How could I proceed to display long static text ?</p>
  
  <p>Here is my xaml :</p>
  
  <pre><code>            &lt;ScrollViewer Margin="8"&gt;
              &lt;TextBlock x:Name="LegalTextBlock" TextWrapping="Wrap" Foreground="Black" /&gt;
          &lt;/ScrollViewer&gt;
  </code></pre>
