> The issue is that buffer 3 is supposed to be fixed-size. This is true if you 
use `C-u N C-x ^' for re-dimensionning, but it is not true if you try to do it by 
mouse, in that case buffer 4 is fixed-size instead.

FWIW this is a bug in `adjust-window-trailing-edge' which was already
reported as bug#3689, compare

Please have a look.
