So IFS whitespace only if part of $IFS.

  Any  character in IFS that is not IFS whitespace, along
  with any adjacent IFS whitespace characters, delimits a field.

So this "adjacent" even if *not* part of $IFS.

I am genuinely curious how you concluded this, given the definition you
previously quoted.

  A sequence of IFS whitespace characters is also treated as
  a delimiter.

So this means that *regardless* of whatever $IFS is, the three IFS
whitespace characters are $IFS anyway *if* that is set to

a nin-empty non-default value.

Nonsense.
