Happens when re-ordering more than one node at once, via space tree:

1. Set top level (e.g. Home page) and lower level to non-alpha by manual ordering.
2. Go away.
3. Come back and set top level and lower level to alpha by clicking the "A".
4. Now click the undo arrow to revert the top level to non-alpha. (Leave the lower level as alpha i.e. do not click the arrow.)
5. Go away.
6. Come back — the top level is alpha. It should not be. - SM"
