title: TCPDF Textfield issues with default value
body: <p>I'm trying to create a PDF file with a form. I'm using php and tcpdf.
  The text fields need to be precisely positioned to fit the image in the background. 
  Some of the text fields have default values (via the 'v' attribute).</p>
  
  <p>The issue is that when I click the text field to edit the contents, the text moves a few pixels to the side (probably because of the border around the active input field). When the input loses focus, the text does not return to the original position.</p>
  
  <p>I've tried to visualize the problem with these screenshots:</p>
  
  <p>(note the text position relative to the line below)</p>

  <p>My form default settings:</p>
  
  <pre><code>$pdf-&gt;setFormDefaultProp(array('lineWidth'=&gt;1, 'borderStyle'=&gt;'solid', 
  'fillColor'=&gt;array(), 'strokeColor'=&gt;array(255, 128, 128)));
  </code></pre>
  
  <p>This is the code for the field:</p>
  
  <pre><code>$pdf-&gt;TextField('test', 47, 6, [], ['v' =&gt; 'test(12)'], 8, 13);
  </code></pre>
  
  <p>What I have tried so far: </p>
  
  <ul>
  <li><p>setting the <code>lineWidth</code> to <code>0</code>, but while the border is no longer visible, the text still moves.</p></li>
  <li><p>setting the <code>borderStyle</code> to <code>'none'</code>, same result.</p></li>
  <li><p>setting the <code>strokeColor</code> to <code>[]</code>, same result.</p></li>
  </ul>
  
  <p>What I would like to do:</p>
  
  <ul>
  <li>set a padding to the default value (or otherwise influence its positioning)</li>
  </ul>
  
  <p>or</p>
  
  <ul>
  <li>remove the border from the active form field (not just make it invisible)</li>
  </ul>
  
  <p>I noticed the same behavior on the TCPDF example here: <a href="https://tcpdf.org/examples/example_014/" rel="nofollow noreferrer">https://tcpdf.org/examples/example_014/</a></p>
  
  <p>If you click into the address field, the text moves up and to the left.</p>
