Block refresh is not working except for admin if argument is current-page:user

Block refresh is:
- always working when the argument is [current-user:user];
- not working when the argument is [current-page:user].
But when there is an ajax event in the views (a flag button views field which is pressed for instance), the block refresh is loading and working, after being triggered by the ajax event.
After searching in the file I found that the scope of the js is 'footer'.
I changed it to 'header' just to see and it works in all situations.
I currently don't know how to suggest a patch, I am not there yet, hopefully arriving there in a few weeks or months. I'll suggest this later on if there aren't any reason why the scope should stay in footer.

The file is block_refresh.module line 19 :

function block_refresh_init() {
  if (user_access(BLOCK_REFRESH_ACCESS_CONTENT_PERMISSION)) {
    <strong>drupal_add_js(drupal_get_path('module', 'block_refresh') . '/js/block_refresh.js', array('scope' => 'footer'));</strong>
    drupal_add_css(drupal_get_path('module', 'block_refresh') . '/css/block_refresh.css');
    drupal_add_js(array(
      'block_refresh' => array(
        'settings' => variable_get('block_refresh_settings', array()),
        'args' => arg(),
        'query' => block_refresh_get_query_as_string(),
      )
    ), 'setting');
  }
}
