oldfiles picker : when i select a file out of cwd, the root dir is %home%

[Jaehaks]

Description

I cannot find any case like me

i use default configuration about oldfiles picker.
my nvim configuration path is C:/Users/User/.config/nvim.
and %home% environment variable is C:/spb_data

if i call oldfiles picker in c:/Users/User, and pick a configuration file is opened well.
if i call oldfiles picker in c:/Users/User/.config/nvim/plugin/lsp and select the oldfile test.lua in parent directory of it like /plugins,
empty file open has %home%/.config/nvim/plugin/test.lua
although the absolute path of test.lua is shown with c:/Users/User/.config/nvim/plugin/test.lua

Does not oldfile picker open parent file?

additionally, sometimes duplicated oldfiles are listed in picker like
c:\Users\User.config/nvim/init.lua
c:\Users\User.config\nvim\init.lua

is this bug?
