Those lines run your commands in clean shells.  They are supposed
to demonstrate that I am not seeing the behavior that you are seeing.
I also don't see it using a function in an older version of zsh.

    % /bin/zsh --version
    zsh 5.3 (x86_64-apple-darwin18.0)
    % /bin/zsh -fc '() { read -u 0 -t -k }'
    %
