It seems like the visibility property on a parent heading overrides
the visibility property on a child heading - is this expected? e.g.
when I have the raw text:
* Foo
:PROPERTIES:
:VISIBILITY: content
:END:
** Bar
:PROPERTIES:
:VISIBILITY: folded
:END:
*** Baz
... I would expect (and would like) to see
* Foo...
* Bar...
that is, where Foo shows only the content below it, and Bar has all of
its children folded. Instead, I get
* Foo...
* Bar...
* Baz...
i.e., behavior like if Foo and Bar both "had their visibility" set to
"content" (I'm aware that's not how the internals work but I'm not
sure how else to articulate what I mean). Is there a way to prevent
this and get the behavior I'd expect?
This behavior was reproduced with straight.el on Org mode version
9.5.2 (9.5.2-gbc8c3e @ /home/john/.emacs.d/straight/build/org/, GNU
Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.27, cairo
version 1.17.4) of 2021-03-26, with org-startup-folded set to nil
(without which the visibility properties don't take effect).
Best,
John

The behaviour you observe is because
org-cycle-set-visibility-according-to-property explicitly ignores all
the VISIBILITY properties in all the descendent headings of a heading
with VISIBILITY property. i.e. VISIBILITY property of Bar is ignored
when its ancestor Foo has VISIBILITY property.
This behaviour is not documented in the manual:
>> Furthermore, any entries with a ‘VISIBILITY’ property (see *note
>> Properties and Columns::) get their visibility adapted accordingly.
>> Allowed values for this property are ‘folded’, ‘children’, ‘content’,
>> and ‘all’.
I would say that the existing behaviour is a confusing and might be
considered as a bug. However, it may not always be straightforward how
to deal with different combinations of VISIBILITY setting for
ancestor/descendent headings. Consider the following example:
* Foo
:PROPERTIES:
:VISIBILITY: folded
:END:
** Bar
:PROPERTIES:
:VISIBILITY: content
:END:
*** Baz
Foo is supposed to be folded, but it is unclear how to process Bar.
Should Bar's contents be visible? Should it be folded?
Best,
Ihor

My conclusion is that Bar should be visible. This will be consistent
with how VISIBILITY overrides document-wide STARTUP settings.
Also, the comment in one of Org tests I was concerned about was
inaccurate - it tested for a slightly different bug.
Fixed, on main.
