152027 - Menu scroll buttons should appear only when it is possible to scroll in that direction

Status: VERIFIED DUPLICATE of bug 76828

(SeaMonkey :: Bookmarks & History, defect)

When there are more bookmarks in the folder than space available, scroll buttons
appear at the top and bottom of the bookmark menu.
However, if it is not possible to scroll up (we are at the top of the list for
example), there should be no scroll button there.

Reproducible: Always
Steps to Reproduce:
1.Fill a folder with a lot of bookmarks
2.display the folder clicking on any Bookmarks menu.


Actual Results:  scroll buttons appear at the top and bottom of the menu.

Expected Results:  there only should be a button at the bottom. The top button
should appear once there is something to scroll into. Also when we reach the
end, the bottom button should disappear.

The buttons not appearing until needed would be the best behavior IMO. This is
consistent with current bookmark behavior (the buttons are not there until there
are enough bookmarks to fill the screen).

However at the very least the buttons should be visibly disabled (grayed out or
whatever the standard is), when they are not needed.
