dynamic mode with subHtmlUrl not working

[endrik-h]

Description

lightGallery with subHtml working fine, but why it's not working if I implement it with subHtmlUrl ? With subHtmlUrl gallery was appeared but not showing any caption.

JS code that you use to initialize lightGallery.

lightGallery(document.getElementById('lightgallery'), {
        dynamic: true,
        dynamicEl: [
                {
                    src: '../resources/lightgallery-2.7.1/demo/img/2-1600.jpg',
                    thumb: '../resources/lightgallery-2.7.1/demo/img/thumb-1.jpg',
                    subHtmlUrl : 'subhtml.php?id=1',
                },
                {
                    src: '../resources/lightgallery-2.7.1/demo/img/13-1600.jpg',
                    thumb: '../resources/lightgallery-2.7.1/demo/img/thumb-13.jpg',
                    subHtmlUrl : 'subhtml.php?id=2',
                },
                {
                    src: '../resources/lightgallery-2.7.1/demo/img/4-1600.jpg',
                    thumb: '../resources/lightgallery-2.7.1/demo/img/thumb-4.jpg',
                    subHtmlUrl : 'subhtml.php?id=3',
                }
            ],
}).openGallery(0);

Sample HTML markup

<div id="lightgallery"></div>

Sample subhtml.php

$id = $_GET['id'];
switch($id){
  case 1:
        echo '<h3>test 1</h3>';
  break;
  case 2:
        echo '<h3>test 2</h3>';
  break;
  case 3:
        echo '<h3>test 3</h3>';
  break;
  default:
        echo '<h3>test 0</h3>';
  break;
}
