Input field separators : a string treated as a list of characters
that is used for field splitting and to split lines into words

the shell behaves as if the value of IFS were the space, tab and
newline characters. Implementations may ignore the value of IFS in

were not set.
That seems to indicate that sh is not required to ignore IFS in the
