CSS file not picking up text from other buffers, why?

[benfrain]

If I am writing a CSS file, I often want to write a selector that is based on text already in a different buffer (in HTML or JSX for example).

However, at present, even if a string like 'sausages' exists in a open *.ts buffer, typing .saus does not bring up sausages as an option in the blink menu in the CSS file.

Conversely, the TS file seems able to read the strings from the CSS file and show them when working in the TS file.

How can I adjust my config so that string in open buffers are selectable in the blink menu in CSS files?

Current config:

return {
  keymap = {
    preset = "enter",
  },
  appearance = {
    use_nvim_cmp_as_default = true,
    nerd_font_variant = "mono",
  },
  sources = {
    default = { "lsp", "path", "snippets", "buffer" },
    min_keyword_length = function()
      return vim.bo.filetype == "markdown" and 4 or 0
    end,
  },
  completion = {
    documentation = { window = { border = "single" } },
    menu = {
      border = "single",
    },
    ghost_text = { enabled = true },
    list = {
      selection = {
        preselect = function(ctx)
          return ctx.mode ~= "cmdline"
        end,
        auto_insert = function(ctx)
          return ctx.mode ~= "cmdline"
        end,
      },
    },
  },
  signature = { window = { border = "single" } },
}

Turns out I needed to add sources.providers.lsp.fallbacks = {} which I came to from this issue: #645 (comment)
