title: Summernote edit not displaying scroll bars
body: <p>I am using summernote in a bootstrap modal and set it up as follows:</p>
  
  <pre><code> $('.summernote').summernote({
       toolbar: [
          ['style', ['bold', 'italic', 'underline', 'clear','fontname']],
          ['color', ['color']],
          ['fontsize', ['fontsize']],
          ['height', ['height']],
          ['style', ['style']],
          ['para', ['ul', 'ol', 'paragraph']],  
          ['misc', ['fullscreen','undo','redo']],
          ['table', ['table']]
      ]
      }); 
  </code></pre>
  
  <p>The problems is that no scroll bar appears when I am entering text into the edit area and go below the bottom of the edit area as in:</p>

  <p>What is needed to have the scroll bars appear and constrain the text to stay within the lines?</p>
