Describe the bug There are whitespaces between window titles in the README images, but not in the installed NeoVim/

System information

• OS: linux
• Neovim version: v0.10.0-dev-b74262a
• vim.ui.select backend: builtin
• Dressing config:

local border = require('core.settings').border -- 'single' in this case
require('dressing').setup {
  input = {
    border = border,
    win_options = {
      winblend = 0,
    },
  },
  select = {
    backend = 'builtin',
    builtin = {
      border = border,
      relative = 'cursor',
      win_options = {
        winblend = 0,
      },
      min_height = { 0, 0 },
    },
  },
}

To Reproduce Steps to reproduce the behavior:

1. Rename, select code actions or something else to open dressing features

Screenshots Currently have no screenshot tools in my computer

Additional context Provide a option like space_between_title or let user format the title by themselves.
