It was deliberate, see bug#14816 (and the corresponding change to the
doc string of ispell-region).  With Emacs 29.1, the region is left
around the portion of text that was not yet spell-checked, so it is
more useful for continuing spell-checking.  I guess we could add a
user option to avoid doing that, for those who prefer the old
behavior, but is this really needed?
