bug: Incomplete drive letters in the buffer name on Windows

Neovim version (nvim -v)

NVIM v0.10.0; oil.nvim 9a59256

Operating system/version

Windows 10

Describe the bug

oil.nvim doesn't seem to be appending a colon after the drive letter. I looked for similar issues and found that #326 describes exactly what's happening here. It appears that the issue is expected to be resolved, but I'm still encountering the problem. The path can be viewed using :lua =vim.fn.expand('%').

What is the severity of this bug?

tolerable (can work around it)

Steps To Reproduce

:lua =vim.fn.expand('%')

Expected Behavior

The colon is included after the drive letter.

Repro

-- save as repro.lua
-- run with nvim -u repro.lua
-- DO NOT change the paths
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "runtime", "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",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
        "stevearc/oil.nvim",
        config = function()
            require("oil").setup({
              -- add any needed settings here
            })
        end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

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