I didn't see any response to this in the archives, and the patch
doesn't seem to have made it into 1.5.1.
The patch below seems to help when the form element is at the bottom
of the window, but what's the solution when the list is longer than
the window and part of the list is not visible? I tried using
overflow: auto css, but that seems to just add scroll bars but doesn't
help contain the list in the window.
