title: setWrapText(true) is not working for Label in JavaFX
body: <p>I created a <code>Label</code> in JavaFX which has a contains a lot of text.</p>
  
  <pre><code>Label l1 = new Label("\t\tC-Mark and Attendance Calculator is a simple "
              + "software to find both the C-Mark and monthly attendance "
              + "of students. Inorder to use the features of this software,"
              + " user has to create an account for him first. Then he should "
              + "login using the username and password. He will be able to "
              + "perform all the operations then. Further details are mentioned"
              + " in the 'HELP' section in the user home page.");
  l1.setWrapText(true);
  l1.setTextAlignment(TextAlignment.JUSTIFY);
  </code></pre>
  
  <p>In this code <code>setWrapText(true)</code> is not working. Why? How can I make it work?</p>
