Tags misalign when editing heading in org-mode

Issue type

• Bug report

Environment

Emacs version: 26.3
Operating System: arch linux
Evil version: evil-git-874beba
Evil installation type:
Graphical/Terminal: graphical
Tested in a make emacs session (see CONTRIBUTING.md): yes

Reproduction steps

• Start Emacs
• (org-mode)
• (org-insert-heading)
• (org-set-tags) and add at least one tag
• edit the title of the heading

when editing the title, you will see that adding characters preserves the alignment of the tags; removing characters breaks the alignment.

In vanilla emacs the alignment is always preserved.

a similar thing happens when editing table cells

Tags move

insert state

 <backspace>		;; evil-delete-backward-char-and-join

normal and visual state

 <delete>		;; evil-delete-char
 c			;; evil-change
 d			;; evil-delete
 s			;; evil-substitute
 x			;; evil-delete-char
 X			;; evil-delete-backward-char

emacs state (C-z)

 <delete>		;; delete-forward-char

Tags remain aligned

insert state

 <delete>		;; org-delete-char

emacs state (C-z)

 <backspace>		;; org-delete-backward-char

Opposite behavior

In at least one case, Evil behaves as expected, while vanilla Emacs moves the tags.

The tags don't move when pressing delete in insert state:

 <delete>		;; org-delete-char

<delete> runs the command org-delete-char (found in org-mode-map),
which is an interactive compiled Lisp function in ‘org.el’.

It is bound to <delete>.

(org-delete-char N)

But they move in vanilla Emacs:

 <delete>		   ;; delete-forward-char

<deletechar> (translated from <delete>) runs the command
delete-forward-char (found in global-map), which is an interactive
compiled Lisp function in ‘simple.el’.

It is bound to <deletechar>.

(delete-forward-char N &optional KILLFLAG)

Both when Emacs is started with:

• emacs -q
Org mode version 9.4.4 (release_9.4.4 @ c:/Program Files/Emacs/x86_64/share/emacs/27.2/lisp/org/)Org mode version 9.4.4 (release_9.4.4 @ c:/Program Files/Emacs/x86_64/share/emacs/27.2/lisp/org/)
• and with the org-plus-contrib package is installed:
  Org mode version 9.4.5 (9.4.5-16-g94be20-elpaplus @ c:/Users/username/AppData/Roaming/.org-plus-contrib.emacs.d/elpa/org-plus-contrib-20210412/)

The Evil config (Evil version 1.14.0) uses the default Emacs 27.2, org version:
Org mode version 9.4.4 (release_9.4.4 @ c:/Program Files/Emacs/x86_64/share/emacs/27.2/lisp/org/)

The above was tested with:

GNU Emacs 27.2 (build 1, x86_64-w64-mingw32) of 2021-03-26
Windows 10 Version 2004
