fix(rda): the comparison list froze the settings pane instead of scrolling

overscroll-contain on the conflict box stops the wheel from chaining to
the pane behind it. With a short list — nothing to scroll inside the box
— the pointer over the table therefore froze the whole panel: the page
would not move and neither would the list.

The box scrolls when it has something to scroll; the page scrolls the
rest of the time, which is what containment was preventing.
