`Deol -edit -split -start-insert -toggle` does not start as insert mode

[ujihisa]

• Deol -edit -split -start-insert works fine to start as insert mode
• Deol -edit -split -start-insert -toggle does not start as insert mode, at the 2nd time, with the following vimrc

" git/config/_vimrc_mini
unlet! skip_defaults_vim
source $VIMRUNTIME/defaults.vim

if has('vim_starting')
  set runtimepath+=~/.vimbundles/neobundle.vim
endif

call neobundle#begin(expand('~/.vimbundles'))

let g:neobundle#enable_name_conversion = 1
NeoBundle 'Shougo/deol.nvim'

call neobundle#end()

filetype plugin indent on

set langmenu=en_US.UTF-8
language messages en_US.UTF-8
source $VIMRUNTIME/menu.vim

let g:deol#prompt_pattern = '\[.\{-}\]\$ $'
nnoremap <space>d :<C-u>Deol -split=horizontal -start-insert -edit -toggle<Cr>
let g:deol#shell_history_path = '~/.bash_history'
let g:deol#shell_history_max = $HISTSIZE

function! s:ujihisa_terminal_normal_enter() abort
  if mode() == 't' " It happens only within terminal window, so deol-edit buffer shouldn't matter
    call feedkeys("\<C-\>\<C-n>", 'n')
  endif
endfunction

augroup minimal-vimrc-terminal
  autocmd!
  autocmd BufEnter * call s:ujihisa_terminal_normal_enter()
augroup END

It works for me.

[Shougo]

Please create the minimal vimrc. I have tested minimal vimrc but it works.

[Shougo]

It works for me(again).

[ujihisa]

Updated the description to mention that it only happens when it's executed at least twice, and to include the reproducible vimrc.

[Shougo]

OH, it is reproduce-able on Vim8 only.

[Shougo]

You should not use the BufEnter event. It conflicts with deol behavior.

[ujihisa]

Still trying to find an alternative solution
