Undoing with an active region does not always work as expected if
`comment-dwim' is used.  From emacs -Q:

1. Create a new buffer (C-x b new-buffer RET)

2. Insert A, B, and C on seperate lines as below
   ('*' represents point)

A
B
C*

3. Create an active region over the last two lines (C-SPC C-p C-a)
4. Use comment-dwim (M-; ; RET)
5. Create an active region over the last two lines (C-SPC M->)
6. Undo (C-/):

A
; *
; C

7. Undo again (C-/):

A
;*
; C

8. Undo again (C-/):

A
*
; C

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I can reproduce this in Emacs 29, too.  I wonder whether it's related to
bug#21523 -- it, too, mis-computes the active region at the edges and
includes the wrong thing.
