Clicking outside telescope select window breaks all vim.ui.select actions

[WizardStark]

Describe the bug
Opening a vim.ui.select window using the telescope backend and then clicking outside the popup breaks all subsequent vim.ui.select calls.

See mrjones2014/legendary.nvim#447 for original discovery of this issue and additional context

System information

• OS: [windows/linux/mac] - all three
• Neovim version:

$ nvim --version 
NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1710088188

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/opt/homebrew/Cellar/neovim/0.9.5/share/nvim"

• Is this related to a specific vim.ui.select backend? If so, which one?
  • Telescope
• Dressing config:
  • Provided in minimal init.lua below

To Reproduce
Steps to reproduce the behavior:

1. vim.ui.select({ "apple", "banana" }, {}, function(item) vim.print(item) end) - mapped to <space>a for convenience
2. triple click outside the window
3. <space>a again, or call vim.ui.select

If possible, provide a minimal file that will trigger the issue (see
tests/manual
for examples of short ways to call vim.ui.*):

vim.g.mapleader = " "
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "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)

local plugins = {
	"folke/tokyonight.nvim",
	{ "nvim-telescope/telescope.nvim", dependencies = { "nvim-lua/plenary.nvim" } },
	{ "stevearc/dressing.nvim", opts = {} },
}

require("lazy").setup(plugins, {
	root = root .. "/plugins",
})

vim.keymap.set("n", "<leader>a", function()
	vim.ui.select({ "apple", "banana" }, {}, function(item)
		vim.print(item)
	end)
end)

vim.opt.termguicolors = true
vim.cmd([[colorscheme tokyonight]])

dressing needs to do something when the telescope picker is closed for any reason. I really tried to find a way to achieve that with telescope, and just couldn't. I have now opened them a PR to add the feature (I guess worst-case they'll say how to achieve that otherwise):
nvim-telescope/telescope.nvim#3182

With this in telescope, I confirmed that putting this in the telescope.lua file in dressing at line ~96 fixes the issue:

  vim.api.nvim_create_autocmd("User", {
    pattern = "TelescopePickerClose",
    callback = function(args)
      on_choice(nil, nil)
    end,
    once = true,
  })

I'll followup here when the telescope part of the issue is resolved one way or another.
