Suggestions sometimes are missing keywords

[mikehaertl]

It often happens that a keyword is not suggested even though it definitely appears in some buffer. For example here, where the keyword is literally 2 lines above:

I don't have a procedure to reproduce this. If there's something I can try to debug when it happens, let me know.

Relevant part of my config:

    sources = cmp.config.sources({
      { name = 'vsnip' },
      { name = 'nvim_lsp' },
      {
          name = 'buffer',
          option = {
            -- complete from all buffers
            get_bufnrs = function()
              return vim.api.nvim_list_bufs()
            end,
            -- Use iskeyword instead of default regex to match words
            keyword_pattern = [[\k\+]],
          },
      },
      { name = 'nvim_lua' },
      { name = 'nvim_lsp_signature_help' },
      { name = 'path' },
    }),
