Colouring when first opening neovim

[ghost]

Obviously a low priority bug, but when opening the current directory in neovim using the terminal (e.g., using the command nvim .), colouring for git-status doesn't appear.
If opening fern after first opening neovim (eg. :Fern . or :e .), colouring is present.

The problem can be reproduced on neovim v0.5.0 with the below vimrc.

if exists('+compatible') && &compatible
  set nocompatible
endif

" Disable Vim's native pack feature
set packpath=

" Clone https://github.com/lambdalisue/fern.vim in somewhere
" and specify that directory to the below
" set runtimepath^=~/ghq/github.com/lambdalisue/fern.vim
