dictionary path is only set on entering the first buffer

Env

My config looks like this, and nvim-cmp is loaded on InsertEnter

{
  "hrsh7th/nvim-cmp",
  dependencies = {
    {
      "uga-rosa/cmp-dictionary",
      config = function(_, opts)
        local dict = require("cmp_dictionary")
        dict.setup(opts)
        dict.switcher({ spelllang = {
          en = "/usr/share/dict/words",
        } })
      end,
    },
  },
  opts = function(_, opts)
    local cmp = require("cmp")
    opts.sources = cmp.config.sources(vim.list_extend(opts.sources, {
      {
        name = "dictionary",
        keyword_length = 2,
      },
    }))
  end,
}

Since I set the dictionary path for spelllang=en only, the path will be appended to vim.opt_local.dictionary (notice that it's buffer-local!) on OptionSet

cmp-dictionary/lua/cmp_dictionary/init.lua

Lines 76 to 82 in f076c6b

	if opt.spelllang then
	vim.api.nvim_create_autocmd("OptionSet", {
	group = id,
	pattern = "spelllang",
	callback = callback,
	})
	end

Issue

vim.opt_local.dictionary is only populated when entering the first buffer.
If the first is a "normal" buffer, completion keeps working for later buffers despite vim.opt_local.dictionary being empty, for unknown reasons.
However, if the first buffer is telescope or potentially other special buffers, completion won't work for the entire session.

To reproduce:

# Step	Operation	:setlocal dictionary	Has word completion?
1	start nvim		N/A
2	open a file and enter insert mode	/usr/share/dict/words	Y
3	open another file and enter insert mode		Y

# Step	Operation	:setlocal dictionary	Has word completion?
1	start nvim		N/A
2	:Telescope, then press <esc> to switch to normal mode but not quit telescope	/usr/share/dict/words	N/A
3	quit telescope, open a file and enter insert mode		N

Thanks, it's working now.
