Calling pum#confirm deletes the next word in code

[tmcw]

With this configuration:

inoremap <silent><expr> <TAB>
      \ coc#pum#visible() ? coc#pum#next(1) :
      \ CheckBackspace() ? "\<Tab>" :
      \ coc#refresh()
inoremap <expr><S-TAB> coc#pum#visible() ? coc#pum#prev(1) : "\<C-h>"

" Make <CR> to accept selected completion item or notify coc.nvim to format
" <C-g>u breaks current undo, please make your own choice
inoremap <silent><expr> <CR> coc#pum#visible() ? coc#pum#confirm()
                              \: "\<C-g>u\<CR>\<c-r>=coc#on_enter()\<CR>"

function! CheckBackspace() abort
  let col = col('.') - 1
  return !col || getline('.')[col - 1]  =~# '\s'
endfunction

And with these settings in coc-settings.json:

{
  "suggest.autoTrigger": "trigger",
  "typescript.suggest.autoImports": true,
  "typescript.preferences.importModuleSpecifier": "non-relative",
  "prettier.onlyUseLocalVersion": true,
  "tailwindCSS.headwind.runOnSave": false,
  "javascript.preferences.importModuleSpecifier": "non-relative",
  "typescript.autoClosingTags": false,
  "svelte.enable-ts-plugin": true,
  "[typescript][typescriptreact][javascript]": {
    "coc.preferences.formatOnSave": true
  },
  "suggest.noselect": true,
  "snippets.ultisnips.pythonPrompt": false
}

I get this behavior:

The issue is that I type win, hit tab, accept the suggestion window, but this then deletes the word navigator from the place ahead of this. I think this is a new behavior and I haven't encountered it before - that this completion setup will delete words next to the completed word.

Replace mode is used by default :h coc-config-suggest-insertMode

Thanks - works perfectly! Thanks so much for this project and helping out with questions.

Change suggest.insertMode to insert and try again.
