Just an analyis.
AFAICS, this one comes from a special handling of some custom variables.
In function command-line, we have
;; Re-evaluate predefined variables whose initial value depends on
;; the runtime context. But delay the warning about
;; `user-emacs-directory' being inaccessible until after processing
;; the init file and the command-line arguments, in case the user
;; customized `user-emacs-directory-warning' to nil via those.
(let ((user-emacs-directory-warning nil))
(when (listp custom-delayed-init-variables)
(mapc #'custom-reevaluate-setting
;; Initialize them in the same order they were loaded, in
;; case there are dependencies between them.
(reverse custom-delayed-init-variables))))
(setq custom-delayed-init-variables t)
The list of custom-delayed-init-variables is built by function
custom-initialize-delay. If you grep for that, you'll finds a number of
declarations containing an :initialize with the delaying function.
In a re-dumped Emacs, the variable is not a list, so nothing is done. In
the particular case of transient-mark-mode, the default value, which is
set in C, is nil, so it keeps that value.
