Describe the bug

Looks to be exactly what was happening for https://github.com/stevearc/oil.nvim/issues/60, but when using the floating window. I confirmed the behavior of what was fixed in that PR still worked, but when using require("oil").open_focus() it doesn't seem to set the current buffer as the alternate.

What is the severity of this bug?

minor (annoyance)

Steps To Reproduce

1. nvim -u repro.lua
2. :e somefile1
3. :lua require('oil').open_float() -- somefile1 is set as alternate
4. navigate to another file somefile2, and edit it -- somefile1 is set as alternate
5. :lua require('oil').open_float() -- somefile1 continues to be the alternate, but should be somefile2

Expected Behavior

1. nvim -u repro.lua
2. :e somefile1
3. :lua require('oil').open() -- somefile1 is set as alternate
4. use oil to navigate to another file somefile2, and edit it -- somefile1 is set as alternate
5. :lua require('oil').open() -- somefile2 is the alternate
6. use oil to navigate to somefile2 again, and edit it -- somefile1 is again alternate

-- 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

    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {

        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

Hello,

I've been following the discussion on this issue (#285) and wanted to report that I am experiencing the same problem when using :Oil --float. Like others have mentioned, the alternate file is not being set correctly.

Hi,

First of all, thanks for this awesome plugin, really appreciate your efforts.

I am also facing the same issue when using the float window.
