In the ksh manual, you'll probably find this behaviour documented in
the section on alias expansion.  Alias expansion is performed on the
first word, but not its arguments, barring some exceptions.  One
exception can get you the behaviour you want:  if the first word is an
alias whose expanded value ends in a space, alias expansion is
performed on the next word.  So you can get the behaviour you want in
ksh with:

$ ksh
$ alias ls='ls -F'
$ alias exec='exec '
$ exec ls

Also handy for nohup.
