Very weird issue with checkboxes / radio when more options that fit on the terminal window

[contes]

Although I came across this by pure accident, it might be helpful to others in the future if a fix is implemented.

The issue is that when you navigate with the arrow keys from one option to the other, several options get duplicated and multiple cursors appear. This happens when there are more options declared in either the checkboxes or radio inputs than they fit in the terminal window height.
