Hmm... I think `--with-dumping=none` wouldn't be affected.

IIUC on Android, the first time the users run their Emacs, you run
a special session started from `temacs` with `dump-mode=nil` but where
you do perform a dump at the end of `loadup` and then continue on to
a normal GUI startup?

In that case, I'd expect that this first GUI session works correctly
(w.r.t `custom-reevaluate-setting`), but indeed the subsequent runs
(which presumably make use of the generated pdmp file) will fail to
reevaluate the settings.

Is that what you saw?
