Take the semicolon off the end.  ;-)

And, indeed, Jaap's intuition is correct:

    $topScroll->add_with_viewport($top);
    $bottomScroll->add_with_viewport($bottom);

$top and $bottom are both "natively scrollable" widgets, so
add_with_viewport() actually messes them up.   Just do

    $topScroll->add($top);
    $bottomScroll->add($bottom);
