zvm_bindkey viopp mode doesn't work

[JuanZoran]

General information

Basic examination

• [x] I have read through the README page
• [x] I have the latest version of zsh-vi-mode
• [x] I have tested with another terminal program

Problem description

I prefer use ijkl for cursor move, so I try to map all hjkl motion for that the normal mode and visual mode, it works well, but in viopp mode, it doesn't work

Reproduction steps

1. use this configuration

# NOTE : Utility
local function set_keys() {
    local mode=$1
    for key value (${(kv)keys}); do
        zvm_bindkey $mode $key $value
    done
}

local function unset_key() {
    local mode=$1; shift 1
    local keys=("$@")
    for key ($keys); do
        bindkey -r -M $mode $key
    done
}

function zvm_config () {
    ZVM_INSERT_MODE_CURSOR=$ZVM_CURSOR_BLINKING_BEAM
    # ZVM_NORMAL_MODE_CURSOR=$ZVM_CURSOR_BLINKING_BLOCK
    # ZVM_OPPEND_MODE_CURSOR=$ZVM_CURSOR_BLINKING_UNDERLINE

    ZVM_VI_INSERT_SURROUND_BINDKEY=s-prefix # zsh-vim-surround support
    ZVM_VI_INSERT_ESCAPE_BINDKEY='^S'
    ZVM_VI_SURROUND_BINDKEY='s-prefix'
    ZVM_READKEY_ENGINE=$ZVM_READKEY_ENGINE_NEX
    ZVM_VI_HIGHLIGHT_BACKGROUND=#89e051           # Hex value
    ZVM_VI_HIGHLIGHT_FOREGROUND=#1d202f           # Hex value
}

function load_ins_key () {
    keys=(
        '^p' up-line-or-search
        '^k' menu-select
        '^n' menu-select
        '^v' describe-key-briefly
        '^b' backward-word
        '^f' forward-word
    )
    set_keys viins
}
zvm_after_init_commands+=(load_ins_key)

function zvm_after_lazy_keybindings() {
    # Unbind key
    unset_key viopp \
        j k iW iw ia

    local -A keys

    keys=(
        h zvm_enter_insert_mode
        H zvm_insert_bol

        i up-line-or-history
        k down-line-or-history
        j vi-backward-char
        l vi-forward-char
        J vi-beginning-of-line
        L vi-end-of-line
    )
    set_keys vicmd


    keys=(
        j backward-char
        k down-line
    )
    set_keys visual

    keys=(
        W select-in-blank-word
        w select-in-word

        i up-line
        k down-line
        J vi-beginning-of-line
        L vi-end-of-line
    )
    set_keys viopp
    # zvm_bindkey visual "i" up-line
    # unset_key visual \
        #     "i^["\
        #     "i "\
        #     "i\""\
        #     "i'"\
        #     "i("\
        #     "i)"\
        #     "i<"\
        #     "i>"\
        #     "iW"\
        #     "i["\
        #     "i]"\
        #     "i\`"\
        #     "ia"\
        #     "iw"\
        #     "i{"\
        #     "i}"
    # visual "h" zvm_readkeys_handler
    # visual "h^[" zvm_select_surround
    # visual "h " zvm_select_surround
    # visual "h\"" zvm_select_surround
    # visual "h'" zvm_select_surround
    # visual "h(" zvm_select_surround
    # visual "h)" zvm_select_surround
    # visual "h<" zvm_select_surround
    # visual "h>" zvm_select_surround
    # visual "hW" select-in-blank-word
    # visual "h[" zvm_select_surround
    # visual "h]" zvm_select_surround
    # visual "h\`" zvm_select_surround
    # visual "ha" select-in-shell-word
    # visual "hw" select-in-word
    # visual "h{" zvm_select_surround
    # visual "h}" zvm_select_surround
}

2. check the viopp mode keybindings:

the zsh told me that it was defined correctly

Expected behavior

try to type dj, it should delete the cursor char and the char left cursor, but it does nothing...
