Preconditions: added an item structure like in attachment
1. Delete Child item - in Trash, in original location column we will see "ezplatform/Parent item"
2. Delete Parent item - in Trash, in original location column we will see "ezplatform" - OK, but for Child item there is also "ezplatform"
3. Pick Parent item and click Restore selected - Parent item is back in ezplatform - OK
4. Go to Trash again and pick Child item (even if its Parent item went back, we still see here that its original location is ezplatform) and click Restore selected - it impossible, there is a message that location of some if could not be found (it is maybe the old location of ezplatform/Parent item), so we can only use another button "restore under new parent" and choose manually Parent item.

Expected behaviour: Supriya put a solution in a comment below.
