do_shortcode关闭不存在的段落

Question

我创建了一个简单的简码来显示标题和左侧的图标。不知何故，将插入一个封闭的（孤立的）

标记来呈现简码。

function tiemme_title_with_icon ( $atts, $content = null ) {
  extract( shortcode_atts( array(
    'ico' => '',
    'text' => 'title',
  ), $atts ) );

  ob_start();

  printf('<div class="title_with_icon"><span class="detail_title ico-%s">%s</span></div>', $ico, $text);

  if($content) {
    echo '<div class="serv_content"><div class="detail__text pad-icon-indent">';
    echo do_shortcode($content);
    echo '</div></div>';
  }

  return ob_get_clean();
}

代码返回以下结果

<div class="title_with_icon">
  <span class="detail_title ico-puntivendita">TITLE</span>
</div>
<div class="serv_content">
  <div class="detail__text pad-icon-indent">
    </p>  <!-- this P tag is the one to remove! -->
    <p>REAL AND GOOD CONTENT</p>
  </div>
 </div>
