Intentionally so.  IIRC, displaying *Choices* was initially even more
rigid - it didn't use 'display-buffer' at all.

The solution is to set 'ispell-choices-win-default-height' to a very
large value so that in practice 'split-window' can never make a window
that high.  If after some time you come to the conclusion that this
trick works satisfactorily, we can mention it somewhere at your choice.
