Bug: broken org-cycle-include-plain-lists integrate [9.3.3 (9.3.3-elpa @ /home/bruce/.emacs.d/elpa/org-9.3.3/)]

[Bruce Tulloch <bruce@metachip.com>]

* Bug Report

  (setq org-cycle-include-plain-lists 'integrate)

  seems to have no effect.

  That is, plain lists are no longer cycling as children of outline headings.

* Example

  This content appears when cycling on Example

  * This plain list line appears (correct)
    * this line also appears (incorrect)
    * this one too (it shouldn't)
  * but this one should appear (and does)
  * as does this one but
    * this should not (but does)
      * and so does this one
* Discussion

  When cycling on the heading, plain lists always appears in the expanded state
  since upgrading to 9.3.3. The plain list will not cycle (as children of the
  heading). It appears that when org-cycle-include-plain-lists is 'integrate it
  is behaving the same as when set to t.

  This changed has appeared since 9.2.1 (which used to work).
