If any other than root level page is selected then page selection dialog will incorrectly open as collapsed showing only root level items not showing the actual selection. Steps to reproduce:

1. Open rich text editor either from showcase or pages editor
2. Create magnolia link to demo-project->about
3. Edit link to open page selection dialog with selected sub node

Now select page dialog is shown without selection. Open demo-project node and observe that about node is actually selected.

Expected result would be that tree is opened to the level of selected subnode. By selecting a root level node there are no problems.
