* Reproducer

Save the following files:

------------------------- /tmp/test.org -------------------------
#+begin_src bash
  foo
  bar
  baz
#+end_src
------------------------- /tmp/test.org -------------------------

------------------------- /tmp/test.el -------------------------
(transient-mark-mode -1)
(setq org-support-shift-select t)
------------------------- /tmp/test.el -------------------------

Then start Emacs as

  emacs -Q -l /tmp/test.el +2 /tmp/test.org

Select the three lines of the source block with `C-3 S-<down>', then
press `M-;'.

For me the resulting buffer looks like:

------------------------- /tmp/test.org -------------------------
#+begin_src bash
  foo
  bar
  baz				# (point)
#+end_src
------------------------- /tmp/test.org -------------------------

where I would have expected:

------------------------- /tmp/test.org -------------------------
#+begin_src bash
  # foo
  # bar
  # baz(point)
#+end_src
------------------------- /tmp/test.org -------------------------

The latter result you get when Transient Mark mode is permanently on.

* My Educated Guess

In the following snippet from `org-comment-dwim'

  (org-babel-do-in-edit-buffer (call-interactively #'comment-dwim)))

the buffer-local setting of `transient-mark-mode' (having value `(only)'
when a region is shift-selected) from buffer test.org does not get
transferred to the intermediate source buffer.  However, function
`comment-dwim' relies on that to decide whether to operate on point or
on region:

  comment-dwim is an interactive native-compiled Lisp function in
  ‘newcomment.el’.

  Call the comment command you want (Do What I Mean).
  If the region is active and ‘transient-mark-mode’ is on, call
  ‘comment-region’ (unless it only consists of comments, in which
  case it calls ‘uncomment-region’); [...]

So probably somewhere in `org-babel-do-in-edit-buffer' the value of
`transient-mark-mode', if it is buffer-local and differs from the
default value, should be transferred to the intermediate source buffer.

I found that current bugfix (commit 
1014296344a75fa08e0a8814e4fbbd767e7eba4c) brought new bugs.

Step to reproduce:

1. Set these variables.

(setq org-src-content-indentation 4)

(setq org-src-preserve-indentation nil)

2. Try to comment some lines in a source block. For example, line foo 
and bar.

#+begin_src emacs-lisp
     (setq foo 1)
     (setq bar 2)
     (setq buz 3)
#+end_src

Expected:

#+begin_src emacs-lisp
     ;; (setq foo 1)
     ;; (setq bar 2)
     (setq buz 3)
#+end_src

Got:

#+begin_src emacs-lisp
     ;; (setq foo 1)
     ;; (setq bar 2)
     ;; (setq bu
           z 3)
#+end_src

Then I found that there is a problem in function 
`org-comment-or-uncomment-region` in lisp/org.el.

in func `org-comment-or-uncomment-region` :

#+begin_src emacs-lisp

(let ((offset (- end beg)))
     (save-excursion
       (goto-char beg)
       (org-babel-do-in-edit-buffer
        (comment-or-uncomment-region (point) (+ offset (point))))))
#+end_src

the value of `offset` is wrong, it became `Expected_Value + 
Org_Src_Indent * Lines_To_Comment`, in the example which is 8 chars more 
than expected.


Thanks.
