In `SetTitle`, `CopyUIItem()` returns a `UIItem *` backed by the same class
that `item` is, which is not guaranteed to be a UIPrimativeItem object. That
guarantee only holds in the `SetBackground` function.
Fixes: df209742fc (bogus cast added)
Fixes: 51fb3fea60 (added UITextItem in the options dialog)
