Can't find a node that matches selector if it's parent matches selector

[maxstar]

<parent attribute="something">
    <child attribute="anything"></child>
</parent>

$dom->find('[attribute]') returns only parent node.
In Selector.php

               if ($pass) {
                    // it passed all checks
                    $return[] = $child;
                } else {
                    // this child failed to be matched
                    if ($child instanceof InnerNode &&
                        $child->hasChildren()
                    ) {
                        // we still want to check its children
                        $children[] = $child;
                    }
                }

'else' block must be executed regardless of whether the current node has passed the match or not.
