If RMS confirms that is the case, then I will retract my request that this
be a blocking bug for the next release but I have a feeling the old
behavior was intended.

I think you are misstating what happens a bit or should use some other
phrasing.  It is not that invisible text is ignored, it is simply that
invisible line endings are ignored when computing lines and the text of
invisible lines is paired with any prior visible line as part of it.  Thus,
the text characters within the invisible part are still considered when
sorting but they are not sorted separately from the visible parts.
