[BUG] "close_unsupported_windows = true" close terminal window

[nanozuki]

Describe the bug

The option close_unsupported_windows = true will close the terminal window, event there are "terminal" in sessionoptions.

To Reproduce
Steps to reproduce the behavior:

1. Open nvim
2. use tabnew create new tabpage
3. use terminal open a terminal
4. use SessionSave create session
5. exit and reopen nvim
6. the terminal window is missing.

Expected behavior
Restore the terminal window.

Screenshots
Before close:

After restore, terminal is missing:

Baseline:

Minimal config to reproduce:

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()
require("lazy.minit").repro({
  spec = {
    {
      "rmagatti/auto-session",
      opts = {},
    },
  },
})

vim.o.sessionoptions = "buffers,curdir,folds,help,tabpages,winsize,resize,winpos,terminal,globals"
vim.o.showtabline = 2
vim.o.background = "dark"

Save this file to repro.lua, use nvim -u repro.lua to open nvim with this config.

Additional context

Because there is a "terminal" option in sessionoptions, I think the terminal window shouldn't be close when this option is active.

I use this function to clean buffers before, maybe helps you:

local function clean_buffers()
  local bufs = vim.api.nvim_list_bufs()
  for _, buf in ipairs(bufs) do
    local name = vim.api.nvim_buf_get_name(buf)
    local type = vim.api.nvim_get_option_value('buftype', { buf = buf })
    if name ~= '' and type ~= '' and type ~= 'terminal' then
      vim.api.nvim_buf_delete(buf, {})
    end
  end
end
