Describe the bug

After applying CodeAction, the placeholder order and range for jumping to applyedits are abnormal

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：

  colorscheme habamax
  
  set nu
  set laststatus=2
  set statusline=%<%f\ %h%m%r%=%-14.(%l,%c%V%)\ %P
  set statusline^=%(%1*[%{coc#status()}%{get(b:,'coc_current_function','')}]%*\ %)
  
  packadd coc.nvim
  filetype plugin indent on
  syn on
  
  inoremap <silent><expr> <cr>
              \   coc#pum#visible() ? coc#pum#confirm()
              \ : "\<C-g>u\<CR>\<c-r>=coc#on_enter()\<CR>"
  inoremap <silent><expr> <tab> coc#pum#visible()
              \   ? coc#pum#next(0)
              \   : coc#refresh()
  nmap <F3> <Plug>(coc-codeaction-cursor)
  xmap <F3> <Plug>(coc-codeaction-selected)
  nmap <C-k> <Plug>(coc-diagnostic-prev)
  nmap <C-j> <Plug>(coc-diagnostic-next)
  nmap K :call CocActionAsync('doHover')<CR>
  xmap K <cmd>call CocActionAsync('doHover')<CR>
  
  augroup coc_user
    autocmd!
    " Update statusline
    autocmd User CocStatusChange redrawstatus
  augroup end

• Plugin: coc-rust-analyzer

• Rust-Analyzer from https://github.com/rust-lang/rust-analyzer/releases/tag/2025-11-17

• Run cargo new foo && cd foo

• Start (neo)vim with command: vim -Nu mini.vim src/main.rs

  fn main() {
      loop {
          break;
          continue;
      }
  }

• Operate vim.

  1. On loop input <F3> use Add Label

  2. Input some <c-j>

     1. expected selected 'l before : loop
     2. unexpected cursor before loop
     3. unexpected selected range " 'l" after break, expect "'l"
     4. unexpected selected range " 'l" after continue, expect "'l"

  Current:

  fn main() {
      'l: loop {
          break 'l;
          continue 'l;
      }
  }

  Output edits:

  fn main() {
      ${1:'l}: loop {
          break ${2:'l};
          continue ${0:'l};
      }
  }

If I understand correctly, the output result is correct but <C-j> jumping and selected range is abnormal. Tested with VSCode, after action applied, Tab will jump to break then continue.

Looks like something is broken in SnippetTextEdit feature.

If I understand correctly, the output result is correct but <C-j> jumping and selected range is abnormal.

Yes, only jumping and selected range are abnormal
