filename_first doesn't works with buffer list

[Wordluc]

Description

When using Telescope.nvim to display buffers, the buffer list does not show the file names first. This issue occurs even though the path_display option is set to show file names first (for files/grep, this setting works correctly).

Neovim version

NVIM v0.9.5
Build type: RelWithDebInfo
LuaJIT 2.1.1703942320

Operating system and version

Windows 11

Telescope version / branch / rev

master

checkhealth telescope

Steps to reproduce

set the options
path_display = { filename_first = { reverse_directories = false } }
after (restart nvim), the options is applied of the other search but buffer

Expected behavior

see each each buffer with the name first

Actual behavior

some buffer have the name first other not

Minimal config

require("telescope").setup {
	defaults = {
		path_display = {
			filename_first = {
				reverse_directories = false
			}
		},
		file_ignore_patterns = { "./^.git/*", "./node_modules/*", "node_modules", "^node_modules/*", "node_modules/*" },
	} 
}
local builtin = require('telescope.builtin')
vim.keymap.set('n', '<leader>ff', builtin.find_files, {})
vim.keymap.set('n', '<leader>fvv', function()
	builtin.grep_string({ search = vim.fn.input("Grep > ") })
end)
vim.keymap.set('v', '<leader>fvv', function()
	vim.cmd('noau normal! "ay"')
	builtin.grep_string({ search = vim.fn.getreg("a") })
end)
vim.keymap.set('n', '<leader>fb', function()
	builtin.buffers({ sort_mru = true })
end)

vim.keymap.set('n', '<leader>fg', function()
	builtin.lsp_references()
end)
vim.keymap.set('n', '<leader>fv', builtin.live_grep, {})

vim.keymap.set('n', '<leader>fs', builtin.tagstack, {})

Bug:
Basically, the path sometimes uses "/" and other times "\". The firstname option works with "\", so I replaced "/" with "\". After that, the option works correctly.
I modified the file: __internal.lua.

Temporary solution used:

		local info = vim.fn.getbufinfo(bufnr)[1]
		info.name = info.name:gsub("[/]", "\\")
		local element = {
			bufnr = bufnr,
			flag = flag,
			info = info,
		}
