bug: Opening multiple buffers at the same time (i.e., with -o or -O) fails to open oil in the second buffer

Neovim version (nvim -v)

NVIM v0.12.2

Operating system/version

Linux 7.0.5-arch1-1

Describe the bug

If one tries to open two buffers at the same time using Neovim's -o or -O arguments, and the second buffer is a directory, the second buffer is always completely blank. It doesn't matter what the first buffer is; it could be either a directory or a file. This behavior cannot be replicated when using Neovim without Oil (i.e., with netrw).

What is the severity of this bug?

tolerable (can work around it)

Steps To Reproduce

Either of the following reproduce the behavior. (Of course, make sure that the directories have files; otherwise a blank buffer would be expected).

nvim -u repro.lua -O file.txt dir/

nvim -u repro.lua -O dir1/ dir2/

Expected Behavior

The second buffer should open with Oil if there are files in the directory.

Directory structure

dir1/file.txt
dir2/file.txt

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

Did you check the bug with a clean config?

• I have confirmed that the bug reproduces with nvim -u repro.lua using the repro.lua file above.
