Describe the bug

Opening an already opened file from another instance throws

Error executing vim.schedule lua callback: /tmp/repro/.repro/plugins/oil.nvim/lua/oil/init.lua:599: Vim:E325: ATTENTION

        vim/_editor.lua: in function <vim/_editor.lua:0>

Is this something we should handle/hide?

Steps To Reproduce

1. touch file
2. nvim -u repro.lua file
3. (In another instance) nvim -u repro.lua, open oil and open file from within oil

Expected Behavior

We could hide the stack trace.

Directory structure

/tmp/repro/repro.lua
/tmp/repro/file

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.

Should be fixed. Thanks for the report!
