I don't see this behavior.

    % zsh --version
    zsh 5.9 (x86_64-apple-darwin18.7.0)
    % zsh -fc 'read -t -k'
    % zsh -fc 'read -u 0 -t -k'
    %

More information about your operating system and zsh version might
be helpful.

I'm looping the list back in.  Please remember to reply to the list
in the future.

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 }'
    %
