Neovim version (nvim -v)

v0.10.0-dev-836+g6d93bdd45

Operating system/version

Mac Ventura 13.5

Describe the bug

When opening a file that has a modeline, strange things happen when opening/closing the command line and triggering completion. Moreover, I see the following error in my debug logs:

Error detected while processing nvim_exec2()..modelines[1365]..OptionSet Autocommands for "filetype":
E12: Command not allowed in secure mode in current dir or tag search
Executing OptionSet Autocommands for "*"
autocommand <Lua 310: ~/.local/share/nvim/lazy/dropbar.nvim/lua/dropbar.lua:70>

Disclaimer that I've been able to reproduce the issue when using noice and dropbar.nvim. Given the above stack trace I originally created an issue there, but I was advised to report it to noice instead.

Steps To Reproduce

1. Save the configuration file above under minimal.lua.
2. In the same directory, create a file with the following content:

A text file.

 vim:tw=78:ts=8:sw=2:et:ft=help:norl:

3. Open Neovim with nvim --clean -u minimal.lua test.txt
4. Type :h he<Tab> (trigger command line autocompletion).
5. Notice how Noice's command line get's stuck.
6. Exit Neovim with qa. Repeat step 4 but opening Neovim with nvim --clean -u minimal.lua test.txt -V10mynvim.log
7. Open mynvim.log and search for Error.
8. Notice the errors about incorrectly processing autocommands.

Expected Behavior

For neovim to behave normally.

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  { "folke/noice.nvim", dependencies = "MunifTanjim/nui.nvim", config = true },
  { "Bekaboo/dropbar.nvim", config = true },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here
