access_check visibility plugin does not work with internal Drupal paths

In plugins/access/path_visibility.inc:

/**
 * Check for access.
 */
function ctools_path_visibility_ctools_access_check($conf, $context) {
  if (isset($context->data)) {
    $base_path = $context->data;
  }
  else {
    $base_path = $_GET['q'];
  }

  $path = drupal_get_path_alias($base_path);
  $page_match = drupal_match_path($path, $conf['paths']);

  // If there's a path alias, we may still be at the un-aliased path
  // so check that as well.
  if (!isset($context->data) && $path != $base_path) {
    $page_match = $page_match || drupal_match_path($base_path, $conf['paths']);
  }

  // When $conf['visibility_setting'] has a value of 0, the block is displayed
  // on all pages except those listed in $block->pages. When set to 1, it
  // is displayed only on those pages listed in $block->pages.
  $page_match = !($conf['visibility_setting'] xor $page_match);

  return $page_match;
}

If $context->data is set, then a visibility rule of node/30 will never match $base_path = 'node/30', only node/30's alias (if it has one)...

if (!isset($context->data) && $path != $base_path) { ... sigh.

In other words, the plugin only works with internal Drupal paths IF they don't have an alias drupal_get_path_alias() OR when $context->data is not set in the function ctools_path_visibility_ctools_access_check.
