bug#33513: 26.1; emacsclient forgetting keybinds set by tty-setup-hook

[Hadrien Lacour]

Hello, by using these two files:
$ cat ~/.emacs
(add-to-list 'load-path "~/.emacs.d/lisp/")
$ cat -A ~/.emacs.d/lisp/term/st.el | sed 's#\$$##'
(message "Registering st keybinds")
(define-key input-decode-map "^[[1;5A" [C-up])
(define-key input-decode-map "^[[1;5B" [C-down])
(define-key input-decode-map "^[[1;5C" [C-right])
(define-key input-decode-map "^[[1;5D" [C-left])
(define-key input-decode-map "^[[1~" [home])
(define-key input-decode-map "^[[4~" [end])

I get the keybinds I want when using emacs -nw with st, but when using
emacs --daemon and emacsclient, these work only the first time:
$ emacs --daemon
$ emacsclient -nw myfile # no problem, close with C-x C-c
$ emacsclient -nw myfile # from here, tty frames don't remember the bindings
