} You must be using an older version.  In current versions, PS1 is no
} longer read from the environment, so you should set it to empty inside
} the here string.

Setting it in the here-string is too late.  The prompt is printed even
before the here-string is read.

However, I tried it, and PS1 is imported by zsh built from current git.

The parameters not imported are:
    _
    *
    #
    EGID
    EUID
    GID
    histchars
    HISTCHARS
    IFS
    KEYBOARD_HACK
    module_path
    OPTIND
    path
    PS4
    TRY_BLOCK_ERROR
    TRY_BLOCK_INTERRUPT
    UID
    USERNAME
    zsh_eval_context
