phpStorm/Xdebug can't show show child arrays of objects

Question

I'm trying to debug this code:

  public function removeBlankLines() {
    $this->qp->find('br');
  } // <-- break point is here

When I drill down into the $this object (using phpStorm) I can't see the child array I'm interested in. It just displays "can not get property" Screenshot:

I'm "listen for debug connections" feature. I'm running the script from the command line. PHP version:

[bwood@mbp ~]$ php -v
PHP 5.4.24 (cli) (built: Jan 19 2014 21:32:15)

It's all about how such classes (SplObjectStorage, ArrayObject and alike) are implemented internally:

this is because objects of the class SplObjectStorage are not user land PHP objects but special super duper internal ones. A similar situation will happen with many other internal PHP classes.

AFAIK nothing can be done on PhpStorm's side until xdebug will be able to "support" them.

UPDATE: The aforementioned xdebug ticket was resolved for xdebug 2.3.3 quite some time ago (latest stable xdebug version is 2.4.1) and it should be possible to view such classes in debugger.
