LspInfo reports Running in single file mode when current buffer is not in root_dir

[stasjok]

Description

When active buffer is outside of root_dir LspInfo reports root directory as Running in single file mode.

Steps to reproduce

minimal_init.lua:

local lspconfig = require("lspconfig")

lspconfig.lua_ls.setup({
  -- Use dirname as root_dir
  root_dir = vim.fs.dirname,
})

-- Set up lspconfig commands
vim.cmd.runtime("plugin/lspconfig.lua")

-- Make tmpdir
local tmpdir = assert(vim.uv.fs_mkdtemp(vim.fs.joinpath(vim.uv.os_tmpdir(), "lspinfo_repro.XXXXXX")))

-- Open file in tmpdir
vim.schedule(function()
  vim.cmd.edit(vim.fs.joinpath(tmpdir, "file.lua"))
end)

-- Remove tmpdir after vim exit. It won't work if test files were saved there
vim.api.nvim_create_autocmd("VimLeave", {
  callback = function()
    vim.uv.fs_rmdir(tmpdir)
  end,
})

1. Run neovim: nvim --clean --noplugin -u minimal_init.lua. One buffer is active.
2. Run command: :LspInfo. Root directory: /tmp/lspinfo_repro.9qkBbS.
3. Edit any file outside of root dir: :edit /tmp/lspinfo_repro.
4. :LspInfo. Root directory: Running in single file mode.
5. Switch buffer back: :buffer #.
6. :LspInfo. Root directory: /tmp/lspinfo_repro.9qkBbS.
7. Edit any file inside of root dir (change 9qkBbS to your case): :e /tmp/lspinfo_repro.9qkBbS/1234.
8. :LspInfo. Root directory: /tmp/lspinfo_repro.9qkBbS.
9. When switching to buffer created in 3. LspInfo again reports root directory as single file.

it outside of the root then it run in single file mode what's the problem ?

Client itself is not outside of the root dir, but it's wrongly reported as such. The problem is wrong info reported by LspInfo. Maybe a screenshot would help to understand what's the problem?

All those servers are not running in single file mode. They all have its own root_dir. So it's strange to report it like this.

Compare it to this:

I just switched buffer, nothing else changed. Now lua_ls is reported as single file mode, but for nil_ls root directory is displayed correctly.

Checkhealth (all clients has root_dir):

Could you reopen for the time being? It's not urgent, but so that it's not forgotten completely.
