Hi there,

I found this problem when indenting a region with `org-adapt-indentation=t'
and `org-modern-mode' is turned on. I initially posted this issue on the
issue tracker of `org-modern'
[[https://github.com/minad/org-modern/issues/144]], but as the author
suggested, I need to turn to the `org' side. Below is the problem.

When `org-modern' is installed and `org-modern-mode' is enable in a
buffer, the fontification is augmented. See
[[https://raw.githubusercontent.com/minad/org-modern/screenshots/example.gif]]
for a demonstration.  But when I have `org-modern-mode' turned on,
`org-adapt-indentation' to be `t', and indent some region, it becomes:

#+begin_quote
** A level-2 heading
   something

   something

            #+begin_quote
a block
            #+end_quote

and something
#+end_quote

While it should become:

#+begin_quote
** A level-2 heading
   something

   something

   #+begin_quote
   a block
   #+end_quote

   and something
#+end_quote

Here is the reply from minad (author of `org-modern'):

Thanks. I can reproduce the problem. It seems that `org-indent-region'
or `org-indent-line' has issues computing the indentation if there are
invisible/diplay properties on the line. This is not something we can
fix in org-modern, since `org-modern' only augments the fontification
and does not override indentation functionality. It should be repaired
in Org directly if even - maybe ask on the Org issue tracker? I suggest
you either don't use `org-adapt-identation' or set
`org-modern-block-name' to nil. With `org-modern-block-name=nil' the
issue also seems to go away.
