Unexpected behaviour when executing ":LspStart lua" in "init.lua" file

Problem

I have nvim config, looking like this (which I believe is common):

nvim/
  lua/
    <a bunch of .lua files>
  init.lua

When I do nvim init.lua LSP client starts, but in single_file_mode. If I do :LspStop and then :LspStart lua it doesn't start, because it can't find the root directory.

Proposed solution

If parent directory contains lua/ directory, parent should be the root directory, not parent .. "lua/".

What happens

This way the root directory for init.lua is nvim/ and for lua/file.lua is nvim/ as well, instead of what happens now (can't find root directory for init.lua and for lua/file.lua root directory is nvim/lua/)
