Need assistance in figuring out what reformats my code on save

[Steinar Bang <sb@dod.no>]

I am trying to remove the configuration that causes web-mode to reformat
my code when saving, because the formatting breaks in the eslint build
step (because eslint prettier and web-mode disagrees).

I have tried to remove the code which looked like it was doing the
formatting, ie.
  (add-hook 'before-save-hook 'tide-format-before-save)

But even after removing this, and with before-save-hook having the value
nil, reformatting takes place on save.

The reformatting I get are changes to indentation, and are the same
changes I get, when I press TAB on the changed lines.

Are there any other hooks that could be involved?
Is there reformatting on save that don't use hooks?
(I'm assuming it is something in my config but I haven't been able to
determine what)

Thanks!

Emacs version is 27.1 on mac OS/X.

The web-mode/tide configuration in my .emacs, is:
(when (locate-library "web-mode")
  (defun setup-tide-mode ()
    (interactive)
    (tide-setup)
    (flycheck-mode +1)
    (setq flycheck-check-syntax-automatically '(save mode-enabled))
    (eldoc-mode +1)
    (tide-hl-identifier-mode +1)
    (company-mode +1))

  (setq company-tooltip-align-annotations t)

  ;; formats the buffer before saving
  (add-hook 'before-save-hook 'tide-format-before-save)

  (add-hook 'typescript-mode-hook #'setup-tide-mode)

  (require 'web-mode)
  (add-to-list 'auto-mode-alist '("\\.tsx\\'" . web-mode))
  (add-hook 'web-mode-hook
            (lambda ()
              (when (string-equal "tsx" (file-name-extension buffer-file-name))
                (setup-tide-mode))))
  (flycheck-add-mode 'typescript-tslint 'web-mode))
