Nvim opens a [No Name] buffer when started on a directory

[saccarosium]

Neovim version (nvim -v)

NVIM v0.6.1

Vim (not Nvim) behaves the same?

no, Works fine on Vim 8.2

Operating system/version

macOS 12.1 Monterey

Terminal name/version

Terminal.app 2.12

$TERM environment variable

xterm-256color

Installation

Homebrew

How to reproduce the issue

nvim -u NORC .

Expected behavior

This should start nvim with a single netrw buffer.
The status line should indicate the path followed by "[netrw]".

Actual behavior

It opens 2 buffers, the netrw one and a "[No Name]" one.
The status line mixes both names and says "[No Name] [netrw]"

Essentially it seems like you see the right netrw buffer and can interact with it, except nvim kind of believe it is on the "[No Name]" buffer.

The main issue for me is that it also places the "[No Name]" buffer as the current buffer. So if I open a file in the directory listing and then press CTRL-^, I expect to be back on the netrw buffer. But I end up on the real "[No Name]" buffer that is empty. I say "real" because when landing, it thinks I am on "[No Name]" but what I see and interact with is really the netrw buffer.
