Current page is not in sort order after loading more entries in the tree

Steps to reproduce:

1. Create at least 17 pages in a space
2. View the last page
3. Click on the more link in the navigation tree to view all pages of the space

Expected result:

The current page is the last entry

Actual result:

The current page is displayed before the loaded entries, thus the sort order is broken:

Before expanding:

After expanding (note the order 28, 27, 29 at the end):

The same is also true for the tree in the breadcrumbs. I Just noticed that also the highlighting of the current entry is lost after expanding the tree. Either this can be fixed while fixing this issue or a new issue should be opened.
