Drop-down menus allow infinite scroll

[dep]

In Ubuntu 10.4 RC and previous releases

1. Open any GTK application that has a drop-down menu (Empathy, Firefox -> save as, GIMP, etc)
2. Position the application window so that when the drop-down menu is opened it touches the lower edge of the screen
3. With the mouse wheel, you can now scroll up infinitely

See the attached screenshot from Empathy

Thank you for your bug report. The issue is an upstream one and it would be nice if somebody having it could send the bug the to the people writting the software (https://wiki.ubuntu.com/Bugs/Upstream/GNOME)

The importance of this bug anything but low.
For example, at a resolution of 800x600, when you first try to set up an account in Empathy and you click to choose a provider from the list, the drop-down menu touches the lower edge of the screen. Without scrolling or doing anything, at the top of the menu there is a lot of empty space that shouldn't be there. If you scroll up, that space becomes bigger.

This is not a duplicate. Bug 388633 talks about extra whitespace in the Gtk combo box. This bug is about the ability to scroll down infinitely past the end of the combo box items. If you scroll down a long way then you have to scroll back just as far to see the list of items again.

This bug occurs only when either the list is so long or the window is positioned near a screen edge so that both ends of the list are not visible at once when the combo is opened. You can then scroll either up or down (depending on which end is hidden) indefinitely past the end of the combo list. However, if you scroll to the other end (i.e. the end that was not visible when the combo opened) the problem goes away until you reopen the combo.

This is not a major issue but it affects a huge number of applications and makes Gtk appear broken. It is much more apparent for large combo box lists.
