gtk scroll bar deficiency

I just built emacs with gtk for the first time and I was struck by the
change in the scroll bar behavior (specifically, the location of the
sliding "scroll thing" - what is its official name anyway?).

before: when the whole buffer is visible, the scroll thing in the bar
occupies the whole scroll bar (clearly indicating that everything is
visible); when the bottom of the buffer is visible, the scroll thing is
at the bottom of the scroll bar. this is also the behavior of gedit,
firefox, openoffice, gnumeric et al, and I like it.

now: when the whole buffer is visible (more generally, when the bottom
is visible), the scroll thing does not reach the bottom of the scroll
bar - you can scroll down and, as the bottom of the buffer scrolls up,
the scroll thing reaches the bottom of scroll bar (while decreasing in
its size). this is the behavior of vim, and I hate it.

is this change intentional?
it looks like a bug to me...

Sam.
