[bug]: compdef is not defined after loading zinit

[jankatins]

What happened?

I try to call compdef in an sourced alias file. According to https://github.com/zdharma-continuum/zinit?tab=readme-ov-file#calling-compinit-without-turbo-mode, compdef should be defined after sourcing zinit, but it isn't:

I'm using this code to load zinit (not sure where I got it from, it's ages since I installed zinit).

if [[ ! -f $HOME/.local/share/zinit/zinit.git/zinit.zsh ]]; then
    print -P "%F{33}▓▒░ %F{220}Installing %F{33}ZDHARMA-CONTINUUM%F{220} Initiative Plugin Manager (%F{33}zdharma-continuum/zinit%F{220})…%f"
    command mkdir -p "$HOME/.local/share/zinit" && command chmod g-rwX "$HOME/.local/share/zinit"
    command git clone https://github.com/zdharma-continuum/zinit "$HOME/.local/share/zinit/zinit.git" && \
        print -P "%F{33}▓▒░ %F{34}Installation successful.%f%b" || \
            print -P "%F{160}▓▒░ The clone has failed.%f%b"
fi

source "$HOME/.local/share/zinit/zinit.git/zinit.zsh"
autoload -Uz _zinit
(( ${+_comps} )) && _comps[zinit]=_zinit

# This shows it's not there: compdef not found
which compdef
.zinit-tmp-subst-on
# And now it's there
which compdef && echo "compdef found"

Interestingly, it's also gone after my zinit calls, so I have to set it explicitly around souring the aliases:

# For some reason, comdef is not defined here and this makes it available, so aliases can use it
.zinit-tmp-subst-on
if [ -f ~/.zsh_aliases ]; then
    source ~/.zsh_aliases
fi
if [ -f ~/.zsh_aliases_local ]; then
    source ~/.zsh_aliases_local
fi
.zinit-tmp-subst-off

... in the last place of the file ...

# Load the real completion system
# Last to let aliases also define completions
autoload -Uz compinit
compinit
# Load completions which were intercepted by zinits fake compdef function
zinit cdreplay -q
