Nokia N97 mini - Why can I not view the full note text added to the contact details?

When selecting a contact in the Contacts menu, the note in the contact details is not fully shown if the length of the note exceeds the space available for showing the text. The whole text can be seen by tapping the right-hand side tab in the upper menu and entering the contact details menu. The note can be viewed by tapping "Note" in this menu.
