Steps to repro:
1. Enable Label, Tags and Comment columns
2. Select any item you want in the List
3. Set some label/tag/comment to such item
4. Now in the Address Bar execute
renameitem("John")
- the item will be renamed accordingly and keep its tags5. Execute once again
renameitem("John")
- the item will lose the tags! (you won't notice it immediately, you have to refresh the List)
