This is an artifact of how the display code steals space from
windows.  The drag code calls enlarge-window and the dispay code
does the dirty work.  I haven't looked at the C code to see the
space stealing algorithm.  I do know, from observation, that it
is different from the one used in FSF Emacs.

I also note the minibuffer size changes don't last long under
XEmacs.  Drag the bottommost modeline upward and then use C-x b to 
switch buffers... poof, the minibuffer is back to one line high.
I don't know what is resetting it.
