I could never reproduce this ksh behavior, but I finally figured out
that ksh93 does this only for login shells.  Non-login shells behave
as bash does.

If you want to emulate that behavior when login shells terminate, add
something similar to the following to ~/.bash_logout:

_JP=$(jobs -rp)
[ -n "$_JP" ] && {
        echo "You have running jobs"
        jobs -r
        echo -n "kill running jobs? [y/n] "
        read ans
        case "$ans" in
        y*|Y*)  kill $_JP 2>/dev/null ;;
        *)      ;;
        esac;
}
