Steps to reproduce the issue:

1. Create the following site hierarchy:

Site 1
---Site 1.1
------Site 1.1.1
------Site 1.1.2
---Site 1.2

2. Create pages for all the previous sites.
3. Add Sites Directory portlet to any page of Site "Site 1.1"
4. Configure the portlet with the following settings: Sites -> Parent

You will see that there is no site displayed in that portlet. However, it should display "Site 1".
