If I cd into an empty directory and try to paste from clipboard nothing happens.

Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating system and version

Arch Linux x86_64 6.0.7-arch1-1

nvim-tree version

latest master

Minimal config

local fn = vim.fn

-- Ignore default config and plugins and define new dirs
local test_dir = '/tmp/nvim-minimal'
vim.opt.runtimepath:remove(fn.expand('~/.config/nvim'))
vim.opt.packpath:remove(fn.expand('~/.local/share/nvim/site'))
vim.opt.runtimepath:append(fn.expand(test_dir))
vim.opt.packpath:append(fn.expand(test_dir))

-- Install packer
local install_path = test_dir .. '/pack/packer/start/packer.nvim'
if fn.empty(fn.glob(install_path)) > 0 then
    packer_bootstrap = fn.system({
        'git',
        'clone',
        '--depth',
        '1',
        'https://github.com/wbthomason/packer.nvim',
        install_path,
    })
    vim.cmd('packadd packer.nvim')
end

-- Setup packer
local packer = require('packer')
packer.init({
    package_root = test_dir .. '/pack',
    compile_path = test_dir .. '/plugin/packer_compiled.lua',
})
packer.startup(function(use)
    use('wbthomason/packer.nvim')
    use('nvim-tree/nvim-tree.lua')

    if packer_bootstrap then
        packer.sync()
    end
end)

-- Plugin setup
local ok, nvimtree = pcall(require, 'nvim-tree')
if ok then
    local tree_cb = require('nvim-tree.config').nvim_tree_callback
    local map_list = {
        { key = '<C-o>', cb = tree_cb('cd') },
        { key = 'u', cb = tree_cb('dir_up') },
        { key = 'F', cb = tree_cb('create') },
        { key = 'c', cb = tree_cb('copy') },
        { key = 'p', cb = tree_cb('paste') },
        { key = 'd', cb = tree_cb('remove') },
    }
    nvimtree.setup({
        view = {
            mappings = {
                custom_only = true,
                list = map_list,
            },
        },
    })
end

Steps to reproduce

As in the GIF

1. Open nvim in a directory with a.txt and inner empty directory (inner) in my example
2. Run :NvimTreeOpen to open the tree
3. Press c to copy the a.txt file into the clipboard
4. Press C-o on inner to cd into that empty directory
5. Press p to paste into this empty directory -> nothing happens
6. Press F to create a file b.txt
7. Press p again to paste from clipboard -> the file a.txt file is now pasted

Expected behavior

After 5. above I expect to be able to paste the a.txt clipboard file

Actual behavior

After 5. nothing happens

Paste also successful if inner/b.txt exists before cd
