find_files throws an error in win_option about deprecated vim.tbl_islist call

[Zooce]

Description

Telescope's find_files shows an error when called with custom dropdown theme:

local dropdown = function(preview)
  return require('telescope.themes').get_dropdown({
    borderchars = {
      { '─', '│', '─', '│', '┌', '┐', '┘', '└'},
      prompt = {'─', '│', ' ', '│', '┌', '┐', '│', '│'},
      results = {'─', '│', '─', '│', '├', '┤', '┘', '└'},
    },
    previewer = false,
    layout_config = { width = 0.7, height = 0.6 },
  })
end

vim.keymap.set('n', '<leader>/f', function() require('telescope.builtin').find_files(dropdown()) end, 'Search Files')

Yes. I have the same error without using dropdown. It only appears once when calling telescope for the first time. It triggers when calling: find_files, git_files, grep_string, keymaps, help_tags and buffers. (Those are the only ones I've used, it's probably triggered in most telescope.builtin functions)

[jamestrew]

Neovim 0.10+ is only compatible with Telescope nightly (master branch) at the moment due to the breaking changes to neovim apis.

I'll try to coordinate downpatching the fix to the breaking apis.

everything is backported to 0.1.x, ill do a 0.1.7 release within the next 10 minutes.

[Conni2461]

should be solved with: https://github.com/nvim-telescope/telescope.nvim/releases/tag/0.1.7

thanks for reporting
