Missing completion items when typing `vim.iter({})`

Problem

When typing vim.iter({}):, completions for the module's functions are missing.

Steps to reproduce

1. Write the following configuration to repro.lua:

   
   local plugins = {
   lspconfig = 'https://github.com/neovim/nvim-lspconfig.git',
   }

vim.env.PATH = vim.env.PATH .. ':' .. vim.fn.stdpath 'data' .. '/mason/bin'

for name, url in pairs(plugins) do local install_path = 'repro/' .. name if vim.fn.isdirectory(install_path) == 0 then vim.fn.system { 'git', 'clone', '--depth=1', url, install_path } end vim.o.runtimepath = install_path .. ',' .. vim.o.runtimepath end

vim.bo.omnifunc = 'v:lua.vim.lsp.omnifunc' require'lspconfig'.lua_ls.setup {}

2. Run `nvim --clean -u repro.lua repro.lua`.
3. Type `ggOvim.iter({}):<C-x><C-o>`.
4. Notice how no LSP completions (such as `any`, `map`, etc) are provided.
