Package: whiptail Version: 0.52.21-3+b1 Additionally: 0.52.20-8 (Buster) + 0.52.19-1+b1 (Stretch)
When using whiptail with the "--scrollbar" option, besides the text scrolling ability, scroll bars should show up on the right side of the whiptail window. This is the case, but the bars start below the lines that are used by the text already, regardless if the text reaches the right side or not. Scrolling and scroll bars only make sense, when the text lines exceed the whiptail window lines, hence in all reasonable cases, the scroll bars are hidden completely.
Scrolling is always possible with this option as expected and as well the issue does not appear on selection fields of --menu and --checklist, which have their own scroll bars, when required, which show up fine. Screenshots can be found here: https://github.com/MichaIng/DietPi/issues/2947
