Opera Bug #200396

Scrollbar corruption caused by margins on content switched dynamically from display:none; to display:block; in overflow:auto; blocks

Fixed in Opera 9.51

IF elements set to display:none; are dynamically switched to display:block; while within a container set to overflow:auto;...
AND IF the appearing blocks have top and bottom margins...
AND IF the appearing blocks amount to more content than the container can hold without scrolling...
THEN a scrollbar appears, but it is corrupted until moused-over or video-refreshed.

No red should appear in the scrollbar area when the button is pressed.
