Describe the bug

This is open happening in Java (using coc-java) when I am in a Maven project. When I accept certain completions, press escape to go back to normal mode, and then press an arrow key, I am put back into insert mode and one of the arrow key codes (A, B, C or D) gets inserted.

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't reproduce it

• Create file mini.vim with：

  set nocompatible
  set runtimepath^=/path/to/coc.nvim
  filetype plugin indent on
  syntax on
  set hidden
  
  
  " load coc.nvim - this will depend on how you use your plugin manager
  call plug#begin('~/.vim/plugged')
  Plug 'neoclide/coc.nvim', {'branch': 'release'}
  call plug#end()
  
  " add some mappings used from README
  inoremap <silent><expr> <TAB>
              \ pumvisible() ? "\<C-n>" :
              \ <SID>check_back_space() ? "\<TAB>" :
              \ coc#refresh()
  inoremap <expr><S-TAB> pumvisible() ? "\<C-p>" : "\<C-h>"
  
  function! s:check_back_space() abort
      let col = col('.') - 1
      return !col || getline('.')[col - 1]  =~# '\s'
  endfunction
  
  " Use <c-space> to trigger completion.
  inoremap <silent><expr> <c-space> coc#refresh()
  imap <C-@> <C-Space>
  
  " use enter to confirm completion
  inoremap <expr> <cr> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>"
  
  " close preview window when completion is done
  augroup coc
      autocmd! CompleteDone * if pumvisible() == 0 | pclose | endif
      " Highlight symbol under cursor on CursorHold
      autocmd CursorHold * :silent call CocActionAsync('highlight')
  augroup END
  
  

• Install Java and Maven

• Generate a Maven project using the following command:

  mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false
  

• cd my-app

• Start (neo)vim with command: vim -u /path/to/mini.vim src/main/java/com/mycompany/app/App.java

• Inside of the main method, type "hello".cont

• Use tab and enter to complete the contains() method.

• Press escape to finish typing and go back to normal mode.

• Press an arrow key to move the cursor. Instead, you will be put back into insert mode and a letter (A, B, C, D) will be entered depending on the arrow key you press.

Screenshots (optional)

I have uploaded a video at the following link.

Please let me know how I can help in any way.

This is occurring on both Macs I use. The one in the video was on macOS Catalina in iTerm 2, but it also happens on a Mac on macOS Mojave in Apple Terminal. Both using vim 8.2.

No idea.

Should be fixed on latest coc.nvim, avoid arrow keys is recommended.
