* [BUG] Child's visibility property is overridden by parent's [9.5.2 (9.5.2-gbc8c3e @ /home/john/.emacs.d/straight/build/org/)

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
