Compare this to the up arrow, and clicking in the area between the up arrow and
the thumb, which is working correctly.

He's talking about the smooth scrolling ("list box animation" in the General
section of Tweak UI from Windows XP PowerToys).  The actual end result is
correct.  When you click, it ends up at the next page of data after it's done

with its list box.

It affects a fair few other programs (the wonderful Inno setup and
various parts of windows itself) so is not LDList specific.
IIRC, there was a code workaround that was applied in Inno but you'd
need to check the newsgroup history.
