avoid redraw loops with ComplexComplexButtonResource

ComplexButtonResource was creating endless redraws.
Testcase:

<table>
  <tr>
    <td>
      <div>
        <button></button>
      </div>
      <div>
        words words words words words words words words words words words
        words words words words words words words words words words words
        words words words words words words words words words words words
        words words words words words words words words words words words
        <span style="white-space:nowrap">And words in a span</span>
        <button></button>
      </div>
    </td>
</table>

This also fixes redraw loops with <button> in combination with
limit_text_width=YES, so we no longer need to disable this option.
